Apply squirrels where needed – Apliku laŭbezone sciurojn

I recently realised that one of the little enjoyments of my day is when I discover words that demonstrate neat uses of word building.

bezoni
to need

Dictionary examples:

laŭbezone
where needed / as need be / as needed

bezonaĵo
requisite / a thing that is necessary

senbezona
needless

Laŭ (“according to” / “following” / “along”) is a frequent culprit for producing interesting constructed words. It works so nicely with so many things. Number 1 is definitely my favourite. It's so succinct, and avoids those different English variations in favour of a single logical version. But I do also like how simply we get to “requisite” using the “aĵ” suffix!

My thoughts:

bezonema
needy

bezonaĉo
base/nasty urge/need

Vortaro.net also has necesbezono as “manko de ĉio, kion postulas la fizika vivo”. What would you say that translates to? Basic/fundamental needs?
