Pronunciation: [tɹˈa͡ɪmiːtə] (IPA) 
Trimeter is a term used in poetry to indicate a line of verse consisting of three metrical feet. The spelling of "trimeter" is rather straightforward, with the initial "t" being pronounced with a voiceless dental plosive /t/. The next syllable, "ri," is pronounced with a mid-central vowel /ɪ/. The final syllable, "meter," is pronounced with an unstressed schwa sound /ə/. Therefore, the word "trimeter" is pronounced as /ˈtrɪmɪtər/.
Trimeter is a term that refers to a type of poetic meter or verse consisting of a line of verse composed of three metrical units or feet. In other words, it is a type of poetic measure that consists of three stressed or unstressed syllables. Each unit or foot in a trimeter line of verse is known as a "trimeter foot."
One of the most common forms of trimeter is the iambic trimeter, which follows the pattern of one unstressed syllable followed by one stressed syllable, repeated three times in a line. This type of trimeter is often found in traditional English poetry and is widely recognized for its regular and sing-song-like rhythm.
However, it is important to note that trimeter is not limited to iambic meter. Other types of trimeter include trochaic trimeter (which features one stressed followed by one unstressed syllable) and anapestic trimeter (which consists of two unstressed syllables followed by one stressed syllable).
Trimeter is a versatile meter that can be used in various poetic forms, including sonnets, hymns, ballads, and even narrative poetry. It allows poets to carefully structure their verses, creating a rhythmic pattern that enhances the overall meaning and impact of their work. By using trimeter effectively, poets can evoke specific emotions in their readers, establish a particular atmosphere, or emphasize certain ideas or concepts.
A poetical division of verse, consisting of three measures.
