also, as well; indicating more of the same.
'too' is an adverb used to modify an adjective or another adverb and can be translated into English as 'very,' 'excessively,' 'also' or 'as well'. It usually appears directly before the adjective or adverb it modifies.
1. The restaurant is too expensive. (excessively)
2. He is excited about his upcoming trip too. (also, as well)
3. This dress is too cute. (very)
when used with a negative verb like 'not,' 'too' can be used to mean 'excessively' or 'more than necessary.' For example, 'The dress is not too expensive.' When 'too' is used in this sentence, it means it is excessively expensive, rather than it is expensive as well.
