Description:

The term 'falu' has to do with arriving at a destination, or being in motion towards a destination.

The derived form 'xafálu' works similarly but with the sense of 'return'. It is more idiomatic to use when referring to returning as an intentional, planned act, whereas having to go back for something is more likely to be expressed as something like 'nox likes falu'.

Verb:

As a verb, 'falu' is a noxaj verb of motion much like noxaj itself, with an absolutive arriver and a dative destination, except it places the focus of the action on the arrival and tends to imply the success of arriving at the destination. Falu is also a verb meaning to orgasm, likely a calque from any of the many languages that use this metaphor.

Falu can also be used in a distintentive pali form which removes all focus on the place  where the arrival occurs.

Noun:

As a noun, 'falu' focuses on the act of arrival. The derived form 'falusyn' is used for more metaphorical kinds of arrival at a destination and is the word for fate, destiny, or outcome. The derived form 'falukija', on the other hand, refers specifically to the place where someone arrives and can be a word for destination, or the state in which something ended up.

As a noun, 'falu' aslo colloquially means an orgasm.

Set Phrase:

There are also the set phrases 'zra falu' and 'noxot zra falu' that are used to mean welcome to assert that one is welcome - see attached article.
