Words that rhyme with Diagonal
On the page, diagonal is a quotidian anchor; on the ear it's a three-syllable word on the front-and-flat /æ/ that ends on a liquid that pulls the line forward. Common words like this gain weight from the company they keep on the line. The headline counts: the strict column is unhelpful here, family-rhyme territory comes up dry, and the slant-by-vowel pool is enormous. The lyric headline: it works as a plain-speech anchor. Assonance is where the modern songwriting toolkit lives for this one.

Why diagonal rhymes the way it does
Pull diagonal apart phonetically and you get a three-syllable word with the short /æ/ (/æ/) as the rhyme-bearing vowel; the close trails through a flowing liquid. In our 54,000-word dictionary the perfect-rhyme pool returns 2 matches, family rhymes 0, additive and subtractive together 20, assonance 6,707, and consonance 4. 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. Practical: skim the strict column first and pick the two or three matches you can sing without thinking. Then move to assonance for the in-between lines. Diagonal reads as more memorable when the strict matches are reserved for the line endings that matter most.
