bollecer

An archaic, now essentially extinct verb meaning to be noisy or to bustle about loudly — you won't find it in everyday modern Spanish, and even in older texts it's rare. Treat it as a historical curiosity rather than usable vocabulary.

• El cronista antiguo escribió que la plaza bollecía de gente. — The old chronicler wrote that the square was bustling and noisy with people.
• En textos medievales, bollecer describe el bullicio de un mercado. — In medieval texts, bollecer describes the noisy bustle of a market.
• Hoy nadie usaría bollecer para describir el ruido de la calle. — No one today would use bollecer to describe street noise.

This verb is so rare that there's no real everyday mistake to flag — bullir or alborotar are what a modern learner should use for 'to be noisy/bustling.'

Often confused with bullir.
