Learn English – What word can fulfill the most parts of speech

parts-of-speechsingle-word-requests

I know there are several parts of speech:

  • Noun
  • Verb
  • Pronoun
  • Adjective
  • Adverb
  • Preposition
  • Conjunction
  • Interjection

There might be others as well. Sometimes a word, depending on how it is used, can fulfill more than one of these classes. For example, the word "run" can be a verb:

I run fast.

or it can be a noun:

Let's go for a run!

What word, taking into account all its definitions, can fulfill the most word classes?
