Description:

The term 'lefo' refers to utilizing something for a purpose, or a use or purpose.

The derived form 'eléfo' is almost the same sense as 'lefo', but it has a weakened or even slightly pejorative tone. In colloquial High Common it does mean something works, that it's functional, but not necessarily any more than that.

This is a reversal from how older speakers use the word. To older speakers, and in older or more formal modern texts, eléfo if actually treated as a stronger or even ameliorated version of lefo.

The purpose of the use can be introduced with the preposition 'u'.
