あげる、くれる、
​もらう
Giving and Receiving
あげる and くれる both mean 'give'. 
But... it's a bit complicated...
  • あげる is used when 'I give to someone' or 'Someone in my group gives to someone'.
  • ​くれる means 'Someone gives me' or 'Someone outside my group gives to someone in my group'. 
​Now would be a good time to check out the video at the bottom of this page!
