“sighs” vs. “size”
Use "sighs" for the noun/verb describing an audible exhale of emotion; use "size" for physical dimensions, scale, or the verb meaning to assess.
sighs
"Sighs" is the plural noun (or third-person singular verb) form of "sigh," describing a long, audible exhale expressing emotions like relief, sadness, or exhaustion ("she gave a heavy sigh," "he sighs whenever the subject comes up"). It comes from Old English "sican," an ancient word imitating the sound of breath being released slowly.
size
"Size" is a noun describing the physical dimensions, extent, or magnitude of something ("the size of the room," "shoe size"), or a verb meaning to sort or measure by dimension ("size up the competition"). It comes from Old French "sise," a shortened form of "assise," originally referring to a fixed standard or seating arrangement, which evolved into the modern sense of measured dimension.
The real distinction
"Sighs" concerns audible breaths expressing emotion, while "size" concerns physical dimensions or scale, and the two words are related only by rough pronunciation similarity for some speakers — many dialects actually distinguish the vowel sounds clearly enough that this pair causes less confusion than true homophones. The mix-up, where it happens, tends to occur in fast, informal writing, especially in text messages or social media posts where a writer types quickly and doesn't notice the swap. A simple check: if the sentence describes an emotional exhale or breathing sound, the word is "sighs" (or the related verb "sigh"); if the sentence describes measurements, dimensions, or scale, the word is "size." The idiom "size up," meaning to assess or evaluate someone or something quickly, is worth knowing as a fixed phrase distinct from any sighing-related meaning — "she sized up the competition" has nothing to do with breathing and everything to do with evaluation. It's also worth noting that "sighs" can describe non-human sounds metaphorically, as when wind through trees is described as "sighing," extending the word's emotional resonance to nature imagery in poetry and descriptive prose. "Size," meanwhile, extends into countless compound and specialized uses — "life-size," "king-size," "oversized" — all consistently describing scale or dimension rather than any emotional or auditory quality.

Memory trick
Picture someone releasing a long breath — "sighs" — versus measuring something with a tape measure — "size." If you can replace the word with "exhales" or "breaths," it's "sighs"; if you can replace it with "dimensions" or "measurements," it's "size." A final test: try replacing the word with "breaths" — if that works, you need "sighs"; if instead "dimensions" or "measurements" fits better, you need "size." Reading the sentence aloud slowly can also help, since "sighs" naturally trails off in a soft, breathy way when spoken, mimicking the very sound it describes, while "size" ends crisply and has no emotional resonance at all.
