To is a preposition.

Too is mostly used as an adverb meaning “besides” or “also”. In some contexts it can mean “excessively“, or to an excessive degree or extent; e.g., “the event was much too lavish for my taste“.  

Two is the number and quantity of having 1 + 1 = 2 (“Can I please have two minutes of silence?“)

What are prepositions?

Think of prepositions as this magic invisible tape that makes sentences stick together and make sense. You don’t really notice them in speech or conversation, but they’re everywhere in English.

Prepositions do more than simply glue parts of sentences togethers, they can also transform into other parts of speech. We use prepositions to indicate place, time, direction, and sometimes abstract connections. They tend to be smaller words, though not always—take a look at some of the most common prepositions:

  • in
  • at
  • on
  • to
  • over
  • above
  • below
  • underneath
  • beneath
  • by
  • next to
  • near
  • inside
