Question: I know that also and too have the same meaning, but what is the difference?
Grammar: Adverbs
Both also and too are adverbs, but they can be found in different places in a sentence:
Also is used before the main verb. It can also be found at the beginning of sentences in informal writing and speech.
Example: I have been to France. I have also been to Spain.
Too is often found at the end of sentences, and it cannot be used at the start of a sentence.
Example: I have been to France. I have been to Spain, too.
Note: Too is commonly used to modify adjectives, though the meaning of this too is different from also.
Example: Spain is too hot.
