Not having the necessary arrangements or adjustments to meet someone's needs or comfort.

Unaccommodated → It is formed from "un-" (meaning not) and "accommodate" (from Latin "accommodare", meaning to make fit or adapt). The word "unaccommodated" means not made fit or not adapted to a particular situation or need.
Think of 'not' ('un-') being added to 'make fit' ('accommodate') — that's why unaccommodated means not made fit.
