IPA: /səˈbɪtəl/
KK: /səˈbɪtəl/
The action of presenting something for consideration or approval.
The contractor's submittal was reviewed by the architect before the project could proceed.
Submittal is formed from "submit" (from Latin "submittere", meaning to send down or yield) and the suffix "-al" (meaning pertaining to or relating to). The word "submittal" refers to something that is sent down or presented for consideration, often in a formal context.
Think of 'submitting' something, which means you are 'sending down' or presenting it for review, and the '-al' indicates it relates to that action.
