If you mistakenly wrote "sememe", but intended to convey a different meaning, here are a few possible correct suggestions. If you meant "meme", referring to a popular internet trend or joke, you may want to use that term. Alternatively, if you meant "scheme", denoting a plan or strategy, that would be a suitable replacement. Lastly, if you were aiming for "semen", which refers to reproductive fluid in animals, that is another accurate term to consider.
