Pronunciation: [tˈa͡ɪm klˈɔːz] (IPA) 
A time clause is a type of dependent clause used to indicate time as part of a sentence. In terms of its spelling, the first syllable of "time" is pronounced /taɪm/ with a long "i" sound, while the second syllable is pronounced /klɔz/ with a short "o" sound. The spelling of "time clause" accurately represents these phonetic sounds. Proper use of time clauses can help to create more complex and accurate sentences in English.
A time clause, in the realm of grammar and language, refers to a specific clause that indicates the temporal relationship between two or more events or actions within a sentence. It is an essential component in sentence construction, particularly in complex sentences that involve multiple clauses. A time clause typically introduces or modifies the main clause's time frame or describes when an action occurs, providing temporal context to the sentence.
Time clauses are commonly introduced by conjunctions or adverbs, such as "when," "after," "before," "while," "since," "as," and "until." These words help establish a relationship of time between events or actions mentioned in the clause and the main clause. Time clauses are often used to express cause and effect, sequential order, or simultaneous occurrence.
For example, consider the sentence: "I will go for a walk when the sun sets." In this case, the time clause "when the sun sets" establishes the specific point in time when the main action of going for a walk will take place.
Time clauses play a significant role in providing clarity, coherence, and precision to sentences, ensuring that the relationship between events or actions is expressed accurately. They allow speakers and writers to effectively communicate chronological information and maintain grammatical structure.
The word "time clause" does not have a distinct etymology as it is a combination of two common English words. However, the etymology of the individual words can be explored.
1. Time: The word "time" can be traced back to the Old English word "tīma" which means "a limited space of time", "a period", or "a season". It has Germanic origins and is related to Old High German "zīm", Old Norse "tími", and Dutch "tijd".
2. Clause: The word "clause" comes from the Middle English word "claus" which means "part of a legal document". It originated from the Latin word "clausula" meaning "a closing, termination, or conclusion". The Latin word is derived from the verb "claudere" which means "to close" or "to shut".
