Words that rhyme with Complexity
The phonetic facts first: complexity is four-syllable, the rhyme-bearing vowel is the short /ɪ/, and the line doesn't close on a consonant at all. It's a concept-word that wants a concrete rhyme to ground it. Its job in a lyric is a word the songwriter reaches for when the line needs scaffolding, holding down whatever line it lands in. When a songwriter asks what rhymes with complexity, the pool tells a specific story: perfect rhymes are not on the table, no family rhymes survive the strict family test, and the assonance bucket is the workhorse here. The interior life of any lyric on this word is going to be the assonance list.

Why complexity rhymes the way it does
Complexity is built around the tight /ɪ/ (/ɪ/); it's four-syllable and ends on an unbuttoned vowel. In our 54,000-word dictionary the perfect-rhyme pool returns 1 match, family rhymes 0, additive and subtractive together 250, assonance 12,750, and consonance 42. That's a narrow strict column with a very deep slant well beneath it. Modern songwriting reads those slants as rhymes; the ear has been trained on them for a century. In the room with a guitar: write toward the strict rhyme first, then go back through and replace the obvious ones with the assonance matches that earned their place. Complexity is a word that benefits from the second pass.
