“sea” vs. “see”
Use "sea" for the body of salt water; use "see" for the verb of perception, understanding, or meeting (and rarely, the noun for a bishop's seat).
sea
"Sea" is a noun naming a large body of salt water, either a specific named sea (the Mediterranean Sea, the Red Sea) or the ocean generally ("life at sea," "lost at sea"). It comes from Old English "sæ," a core Germanic word with cognates in Dutch "zee" and German "See," a word so basic to naming the physical world that its core meaning has barely shifted in well over a thousand years.
see
"See" is most often a verb meaning to perceive with the eyes, to understand, or to meet with someone ("I see what you mean," "let's see each other next week"), though it also survives as a noun in the specific religious sense of a bishop's official seat of authority (the "Holy See"). It comes from Old English "seon," related to German "sehen," and functions in everyday speech almost entirely as a verb of perception or comprehension. The verb also extends into a cluster of idioms worth knowing — "see to it" (to make sure something happens), "see through" (to detect a deception), and "see fit" (to judge appropriate) — none of which have any connection to water at all, but all of which reinforce "see" as fundamentally a verb of perception, judgment, or understanding rather than a physical place.
The real distinction
"Sea" names a body of water; "see" names an act of perception (or, rarely, a bishop's jurisdiction), and despite identical pronunciation the two virtually never cause confusion in meaning, since context makes clear whether a sentence concerns water or vision. The error that does occur is purely a spelling slip during fast typing, especially in phrases where both concepts appear close together, such as "I can see the sea from here," which requires careful attention to keep the two spellings straight in a single sentence. A simple test: if the word can be replaced with "ocean" or "the deep blue water," it's "sea"; if it can be replaced with "perceive," "understand," or "visit," it's "see." Because both words are among the most frequent in the English language — appearing constantly in casual writing, travel writing, and conversation — this is one of the highest-frequency homophone pairs a writer will encounter, even though the actual risk of genuine misunderstanding is low. Beyond the common verb sense, "see" occasionally shows up as a noun in formal or ecclesiastical writing, referring to the official seat of a bishop's authority, as in "the Holy See" or "a vacant see" awaiting a new appointment — a usage far removed from both the ocean and everyday vision, but worth knowing so it isn't mistaken for a typo of "sea" when it does appear in religious or historical texts.

Memory trick
Picture the "a" in "sea" as a wave rolling along the water's surface, while the double "e" in "see" looks like a pair of eyes watching. If the sentence involves eyes or understanding, you need two eyes ("see"); if it involves water, you need the wave ("sea").
