"IMPERMEABLE"
Meaning:
To permeate something is to spread all the way through it. (If rainwater permeates your socks, that feels gross. And if cell phones have permeated the local middle school, they are absolutely everywhere inside that school.)
So, something permeable lets things enter it and spread all through it. (Examples: An Oreo cookie is permeable to milk, yum. A young child's mind is permeable to new ideas.)
And something impermeable doesn't let things enter it and doesn't let things spread all through it. (Example: Being that they're all crotchety and set in their ways, their minds are impermeable to new ideas.)
Pronunciation:
im PER me uh bull
Part of speech:
Adjective.
(Adjectives are describing words, like “large” or “late.”
They can be used in two ways:
1. Right before a noun, as in “an impermeable material.”
2. After a linking verb, as in "The material was impermeable.”)
Other forms:
impermeability, impermeably
How to use it:
Talk about an impermeable area, like an impermeable forest (one that's so dense that you can't walk through it) or an impermeable hallway (one that's so full of piles of things that you can't get across it.)
You can also have an impermeable surface or material, like the impermeable caulk that protects the walls and floors near your tub and doesn't let water seep in.
Figuratively, talk about impermeable minds, an impermeable clique, someone's impermeable confidence, an impermeable argument, etc.
Often you'll say one thing is impermeable to the other thing that can't come in: "the fort is impermeable to attacks," "a resolve that's impermeable to doubts," "her rigid habits are impermeable to suggestions," "his ego is impermeable to criticism."
With the professor's scribbled comment starting with "Okay, but what if...?", a big hole was poked into what I'd thought was an impermeable argument.
He's deaf to criticisms, ignorant of the damage he's already done, and impermeable even to the most reasoned of pleas.
Look away from the screen to explain the definition in your own words. You'll know you understand what "impermeable" means when you can explain it without saying "not porous" or "impassable."
Think of a group, an institution, a hobby, or a career that seems really closed off and hard to get into, and fill in the blanks: "I (still have / once had) the impression that _____ (is / was) impermeable."
Example: "I once had the impression that the world of publishing was impermeable to regular people. But now you can publish absolutely anything, straight to Amazon."

Exploring the archives:
Sometimes when you're searching for the perfect word, a privative prefix like im- can really help. (Privative prefixes take away the meaning of the base word, like you see in "unhappy," "disregard," and "imperfect.")
Say you're trying to think of a word that means "really protected, closed off, and safe from things that try to get in." You could pick "thick-skinned" or "fortified," but the word that really works perfectly means "NOT letting anything in:" impermeable.
Could you recall these other words with privative prefixes? They're the ideal words for talking about...
...making someone not able to think: de____ate,
...things that don't blend well together at all: im_____ible, &
...people or things that don't stop and don't slow down: un____ing.
