Etymology
Origin of boisterous
First recorded in 1425–75; late Middle English boistrous, variant of Middle English boistous “crude, fierce, gross, strong”; of obscure origin; possibly from Old French boisteus “lame,” from boist(e) “box,” also “cavity containing an organ, cavity in a bone” (ultimately from Late Latin buxis; see box 1 ( def. )) + -eus -eous ( def. )
Explanation
Boisterous is a word used to describe someone spirited, loud, and slightly out of control — like someone with a spring in their step and a song in their heart singing to strangers on the street. Boisterous means "loud, clamorous, and unrestrained." Think of children on a playground or a lively party or a litter of puppies as boisterous. This word, which comes from Middle English, can also refer to very intense storms. You could call a hurricane boisterous, but you will most likely hear this word used to describe people.
