Willing to help or adjust to meet someone's needs; friendly and considerate; providing sufficient space or resources.
From Latin 'accommodare,' where 'ad-' means to and 'commodare' means to make fit or suitable. The idea is making something comfortable or suitable for someone.
The root 'commodare' also gave us 'commodity' and 'commodious'—so an 'accommodating' person literally makes you feel like you have abundant ('commodious') space and resources because they're so willing to fit your needs.
