Question

I wonder when I should use the words  "too", "also" and "as well" ?

Answer 1

These words are all used to show similarity or sameness:

• Jeff plays soccer. Greg plays soccer, too.
• Jeff plays soccer. Greg also plays soccer.
• Jeff plays soccer. Greg plays soccer as well.

The only difference is in their placement in the sentence. Too and as well are used at the end of a sentence. (As well is more formal than too). Also usually goes before the verb or adjective.

He likes chocolate.

• I also like chocolate.
• I like chocolate also.
• I like chocolate, too.
• I like chocolate as well.

The apples are delicious.

• The pears are also delicious.
• The pears are delicious also.
• The pears are delicious, too.
• The pears are delicious as well.

The expression as well as can be used in the middle of the sentence, and is similar to “and” or “not only… but also”:

• She bought the necklace. She bought the earrings.
• She bought the necklace and the earrings.
• She bought the necklace as well as the earrings.
• She bought not only the necklace, but also the earrings.

You can also rephrase this to use also, too, or as well:

• She bought the necklace. She also bought the earrings.
• She bought the necklace. She bought the earrings, too.
• She bought the necklace. She bought the earrings as well.
