Uses of ‘Also’, ‘As well’ and ‘Too’ (With Differences)
Also is more formal than as well and too, and it usually comes before the main verb or after be:
– I went to New York last year, and I also spent some time in Washington.
In British English it is not usually used at the end of a sentence.
Too is much more common in spoken and informal English. It is usually used at the end of a sentence:
– ’l’m going home now.’ ‘I’Il come too.’
In British English as well is used like too, but in North American English it sounds formal or old-fashioned.
When you want to add a second negative point in a negative sentence, use not…either:
– She hasn’t phoned and she hasn’t written either.
If you are adding a negative point to a positive one, you can use not…as well/too:
– You can have a burger, but you can’t have fries as well.
