Ooh, well I haven’t done a post about cool stuff words found on twitter for a while, but here’s one
It’s such an unusual-looking word, I wondered if it was a joke word – maybe 3 words stuck together for effect or something – but it’s not.
Here’s what Priberam has to say about it
arcaboiço
(ar·ca·boi·ço)
nome masculino1. Conjunto dos ossos de um vertebrado. = OSSATURA
2. Estrutura óssea do peito. = TÓRAX
3. [Por extensão] Constituição física.
4. [Técnica] Estrutura de madeira de uma construção. = ARMAÇÃO, MADEIRAMENTO
5. Traçado inicial de algo. = DELINEAMENTO, ESBOÇO
6. [Figurado] Capacidade, envergadura (ex.: o técnico não tem arcaboiço para substituir o treinador).
“arcaboiço”, in Dicionário Priberam da Língua Portuguesa [em linha], 2008-2023, https://dicionario.priberam.org/arcaboi%C3%A7o.
So it’s like “bone structure”, but focused on bodily articulation, as distinct from, say, facial bone structure. Nice!

I just realised my reply would have been funnier if I’d said “I’ll look oit for it.” What a waste of a joke!

My dear Colin. Humour and jokes is natural as portuguese words translate to british english
