Awkward is a word that is awkward to explain. It’s usually used to describe things that aren’t smooth or comfortable.
It can mean clumsy:
“She is awkward in the kitchen, she knocks things over all the time”
It can mean that you’re not good at something:
“He played the guitar awkwardly, missing a lot of notes”.
It can mean that something is difficult to use:
“Driving an SUV on narrow streets is awkward”
“After years of using a smartphone I find old flip-phones very awkward.”
When we use it in social situations it’s a combination of all of those things: an uncomfortable, slightly difficult situation that you’re not confident about.
“When my boss found out I was dating his daughter it was very awkward.”
“I always feel awkward at parties where I don’t know anyone.”
“It was very awkward for the young mother as her child wouldn’t stop crying in the toy store.”
So generally awkward is about something being a little uncomfortable. Maybe you’re uncomfortable because you can’t do something well, something is hard to use or you feel a little embarrassed in front of others.
But an awkward situation isn’t a really bad situation, it’s only a little uncomfortable.
