Etymology: The word is built from "giggle" plus the agent suffix "-er", which English has used since Old English to name someone who performs an action. "Giggle" itself is a much older and more sound-driven formation: it imitates the short, bubbling laugh it describes, and it belongs to a family of words in English that echo laughter, such as "gaggle" and "cackle". The suffix has a longer lineage. The "-er" ending descends from Old English "-ere", which came from Germanic roots and, further back, from the Latin "-arius", a suffix that marked a person connected with a trade or activity. Through Old French "-ier" and Middle English "-er", that Latin ending became one of the most productive tools English has for creating names of people, so a giggler is simply someone who giggles.

Synonyms: laugher, chortler, snickerer
