What does 没 mean?
没 (méi) is Chinese's specialized negation word, used for exactly two cases: (1) negating possession or existence — 没有 (méi yǒu, 'don't have / there isn't'); and (2) negating completed past actions — 我没去 (wǒ méi qù, 'I didn't go'). Every other negation in Chinese uses 不 (bù) instead. English speakers should burn this in: you NEVER say 不有 — you say 没有. You NEVER say 不去 for past 'didn't go' — you say 没去. The rule is: 没 = didn't / don't have; 不 = don't / won't / am not. 没有 can be shortened to just 没 before another verb: 我没吃 = 我没有吃 (I didn't eat). 没 also stands alone as a short 'no' in response to 'have you...?' questions.
Character breakdown
not have; (older meaning: to sink / drown — the 氵 water radical on the left)
Memory hook: 没 has the water radical (氵) — think 'sunk under water, gone, not there.'

Don't confuse 没 with
This is THE classic beginner mistake. 不 negates everything EXCEPT 有 and past actions. 不去 = won't go / don't go; 没去 = didn't go. 不是 = is not; 没是 is WRONG (use 不是). 不有 is WRONG — always 没有.
美 ('beautiful') has the same pronunciation family but a 羊 (sheep) top, not 氵 (water). 美国 = America, 没有 = don't have.
