The word 提交 is formed by combining two individual characters, each contributing a key action to create a unified concept. The first character, 提 (tí), carries the core meaning of "to lift", "to raise", or "to present". The second character, 交 (jiāo), means "to hand over", "to deliver", or "to give". When combined, they create a logical, sequential action: one first presents or lifts up something (提) in order to then hand it over (交) to an authority or a system, resulting in the complete meaning of "to submit".
