From As A Preposition


From indicates the starting points of actions, events or spaces. It says when things begin or began.

  • The exhibition was held from Monday to Friday.
  • I work from 10 to 6.

From is not normally used with a perfect tense.

  • The shop was open from morning.
  • I will be here from 3 o’clock onwards.

With a perfect tense we normally use since, not from.

  • I have been working since morning. (NOT I have been working from morning.)
