# cohort /ˈkoʊhɔrt/

A cohort is a group of people who are around the same age, like a cohort of college students who have similar experiences and concerns.

The word cohort was originally used to describe a military unit in ancient Rome.
You can see how this retains traces of the word’s origins: cohorts are bound together by similar circumstances just like a group of soldiers in a military unit.

# awkward /ˈɒːkwərd/ ●●○

If you are awkward, chances are you are uncomfortable. You could feel socially awkward, like when you forget the host's name. Or, you may feel physically awkward, like when you trip on your way to the podium.

Have you ever felt clumsy and that you had two left feet? That is how it is to feel awkward — literally that you are going in the wrong direction.

Awkward is an example of a word literally meaning something and then figuratively meaning something related.

Its Middle English roots are awke, meaning "backhanded," and -ward, to "go in the direction of." So, if you are feeling uncomfortable, or clumsy, it's probably because your hands are connected to you the wrong way!
