Understanding "Of" vs "Form" with Example

Hi there

Thank you for your question. The following sentences state how they should be written correctly;

* She is a friend of mine

* The gift is from you

Below are examples and explanation on when to use each:

• Possessive
• "Of" is used to indicate possession, as in "He's a friend of mine". 
  
  
• Common trait
• "Of" is used with "all" or "both" to describe a shared trait, as in "All of the students in the class enjoy volleyball". 
  
  
• Origin
• "From" is used to indicate where something originates, as in "Jack comes from Portland". 
  
  
• Time
• "From" is used with "to" or "until" to indicate the beginning and end of an action, as in "I work from 8.30 am to 5.00pm every day". 
  
  
• Distance
• "From" is used to indicate distance in relation to somewhere else, as in "The Metro station is nearby and we are only five minutes from the motorway". 
  
  
• Verbs
• "From" is used with certain verbs, like "borrow from", "disappear from", "discourage from", and "prevent from".

 I hope this helps and I look forward to assisting you with any further questions you may have.
