The phrase "to submit an application" means to formally present or file a request, usually in writing, for something that you want or need. This could be a job position, admission into a school or program, a loan, a permit, or any other type of approval or authorization from an organization or authority. The process typically involves filling out and completing the application form with all necessary information, attaching required documents such as transcripts, references, or proof of identity, and submitting it to the appropriate office or person for review and decision.
