Not safe or suitable to drink; it can be harmful or unpleasant to consume.

The water from the river was undrinkable due to pollution.

Conversation

I tried that new tap water in the park, and it tasted completely undrinkable!

Oh no! I heard it was filtered, but it must not be working.

Yeah, I ended up buying a bottled drink instead.

Good call! No one wants to drink something that's undrinkable.

Root Explanation

Undrinkable → It is formed from "un-" (meaning not) and "drink" (from Old English "drincan", meaning to consume a liquid) and "-able" (meaning capable of). The word "undrinkable" means not capable of being consumed as a liquid.

Memory Tip

Think of 'not' ('un-') being added to 'drink' — this helps you remember that 'undrinkable' refers to something that cannot be consumed.
