Have you ever wondered about the phrase "If I were you"? That "were" is a relic of the English subjunctive mood, a grammatical structure that expresses wishes, possibilities, suggestions, or hypothetical situations. While it's becoming less common in modern English, understanding its history provides valuable insight into the evolution of the language. This article will take you on a historical journey, exploring the origins, development, and eventual decline of the English subjunctive mood.

The Origins: Proto-Indo-European Roots and Early English

The subjunctive mood isn't unique to English. Its roots lie deep within Proto-Indo-European (PIE), the ancestor of many modern languages, including English, Latin, Greek, and Sanskrit. PIE possessed a complex system of verb conjugations, including several moods that expressed different degrees of certainty and reality. As PIE evolved into its daughter languages, these moods were simplified and adapted. In Old English, the subjunctive mood was a fully functional part of the verb system. It was used extensively in subordinate clauses to express a range of meanings, including:

• Possibility: Gif hē cyme (If he should come)
• Wish: God helpe ūs (May God help us)
• Doubt: Iċ ne wāt hwæder hē sīe rīċe (I don't know whether he is rich)

The Old English subjunctive was marked by distinct verb endings, clearly differentiating it from the indicative mood (which expresses factual statements) and the imperative mood (which expresses commands). However, the seeds of its eventual decline were already sown.

Middle English: Simplification and Loss of Inflections

The Norman Conquest of 1066 had a profound impact on the English language. French, the language of the ruling class, exerted considerable influence, leading to significant changes in grammar and vocabulary. One of the most important developments during the Middle English period was the simplification of verb inflections. The Old English verb system, with its numerous endings and irregular forms, was gradually streamlined. This process affected all moods, including the subjunctive. Many of the distinct subjunctive endings were lost, and the subjunctive began to resemble the indicative in many cases.

Despite these changes, the subjunctive mood remained relatively common in Middle English. Writers like Chaucer and Malory used it frequently to express a variety of nuances. However, the trend towards simplification continued, and the subjunctive's role began to diminish.

Early Modern English: Standardization and Further Decline

The Early Modern English period (roughly 1500-1800) witnessed the standardization of English grammar and spelling. The invention of the printing press played a crucial role in this process, as it led to the widespread dissemination of written texts and the establishment of grammatical norms. Grammarians began to codify the rules of English, often based on Latin models. While some grammarians advocated for the preservation of the subjunctive mood, the forces of simplification were too strong to resist.

During this period, the use of the subjunctive became increasingly restricted to certain contexts. The were subjunctive (e.g., "If I were you") remained relatively common in hypothetical clauses, and the be subjunctive (e.g., "It is important that he be on time") persisted in formal contexts, particularly in legal and official documents. However, in many other situations, the indicative mood began to replace the subjunctive.

The Rise of Auxiliary Verbs: A Substitute for the Subjunctive

One of the key factors contributing to the decline of the subjunctive mood was the rise of auxiliary verbs, such as should, would, may, and might. These verbs could be used to express many of the same meanings as the subjunctive, often in a clearer and more unambiguous way. For example, instead of saying "If he come," one could say "If he should come." The auxiliary verb should conveys the sense of possibility or uncertainty that was formerly expressed by the subjunctive. As auxiliary verbs became more widely used, the subjunctive gradually became redundant in many contexts.

Modern English: The Subjunctive Today and Usage Examples

In modern English, the subjunctive mood is largely vestigial. It survives in a few fixed expressions and formal contexts, but it is rarely used in everyday speech. There are two main types of subjunctive in modern English:

1. The were subjunctive: This is used in hypothetical clauses, particularly after if and wish. Examples include:
   • If I were a rich man…
   • I wish I were taller.
   • If the weather were better, we could go for a walk.
2. The be subjunctive (also known as the mandative subjunctive): This is used in subordinate clauses after verbs expressing demands, requests, suggestions, or recommendations. Examples include:
   • It is essential that he be present.
   • The doctor recommended that she take a break.
   • I suggest that we leave early.
   • They demanded that the money be returned immediately.

Note that in many cases, the indicative mood can be used instead of the subjunctive, particularly in informal contexts. For example, one could say "It is essential that he is present" instead of "It is essential that he be present." However, the subjunctive is still considered more formal and grammatically correct in such cases. A common error is assuming that the should auxiliary is needed, resulting in the redundant "It is essential that he should be present." Stick with just the base form of the verb for the mandative subjunctive.

Common Mistakes and Misconceptions about the Subjunctive

One common mistake is to confuse the subjunctive with the indicative mood. As mentioned earlier, the subjunctive is used to express wishes, possibilities, or hypothetical situations, while the indicative is used to express factual statements. Another common mistake is to overuse the subjunctive in situations where the indicative would be more appropriate. Remember that the subjunctive is becoming increasingly rare in modern English, and it is often unnecessary in informal contexts.

It's also important to note the difference between the past subjunctive (using "were") and the present subjunctive (using the base form of the verb). The past subjunctive is used in hypothetical clauses that refer to the present or future, while the present subjunctive is used in subordinate clauses that express demands, requests, or suggestions.

The Future of the Subjunctive: Will It Disappear Completely?

The future of the subjunctive mood in English is uncertain. Some linguists predict that it will eventually disappear completely, as it continues to be replaced by auxiliary verbs and the indicative mood. Others believe that it will survive in a few fixed expressions and formal contexts. It is difficult to say for sure what will happen, but it is clear that the subjunctive is no longer as important as it once was. While its usage continues to wane in common parlance, it is still relevant for those in law and other formal professions.

Conclusion: Appreciating the Evolution of English Grammar

The history of the English subjunctive mood is a fascinating example of how language changes over time. From its roots in Proto-Indo-European to its current vestigial status, the subjunctive has undergone a long and complex evolution. While it may be becoming less common in modern English, understanding its history can help us to appreciate the richness and complexity of the language. Whether you're a student of linguistics, a writer, or simply someone interested in language, exploring the history of the subjunctive mood is a rewarding experience.

By understanding where the subjunctive came from, you can better appreciate its nuances and complexities, even as it continues its slow fade from everyday usage. So, the next time you encounter a sentence like "If I were you," remember the long and fascinating history behind that seemingly simple phrase.
