Inhibit means to hold a process or impulse back, keeping it below the level it would otherwise reach. Facilitate means the opposite: to make a process easier and smoother so it runs more freely. One is the brake; the other clears the road.
Both verbs act on a process without doing it themselves, and they pull in opposite directions. Inhibit comes from the Latin inhibere, 'to hold in', and works like a brake — it doesn't stop a thing dead, it restrains and dampens it. Facilitate comes from facilis, 'easy', and works the other way: it removes whatever would have slowed the doing, so the process runs more easily. Both are transitive — you inhibit something, you facilitate something — and reading questions like to test them as a pair.
inhibit
To inhibit is to hold back — to keep something from happening fully or freely. A drug can inhibit the growth of bacteria; shyness can inhibit a student from speaking; cold can inhibit a reaction. The word does not mean to stop dead so much as to restrain, dampen, and limit, keeping a process or impulse below the level it would otherwise reach. To be 'inhibited' is to be held in by self-consciousness, unable to let go.
facilitate
To facilitate is to make a thing easier to do — from the Latin facilis, 'easy', and the precise opposite of impede: where impeding ties weights to the feet, facilitating clears the road ahead of them. Teachers facilitate discussions, enzymes facilitate reactions, new bridges facilitate trade. The word's quiet discipline is that the facilitator never does the thing itself; it removes what would have slowed the doing — often so smoothly that the people helped never notice anyone was working.

Think of a process trying to run. Inhibit is the brake pad on a spinning wheel — it never quite halts the wheel, it just holds it below the speed it would reach on its own; lift the brake and it leaps back. Facilitate is the sweeper running ahead of the traveller, dropping planks into the holes so the walk never breaks stride — it removes what would have slowed things. One word adds friction, the other takes it away. If it makes something harder or slower, it inhibits; if it makes it easier, it facilitates.
inhibit
- iCold weather can inhibit the growth of even hardy seedlings.
- iiFear of judgment inhibits many students from asking questions.
- iiiThe drug works by inhibiting the enzyme the bacteria need to multiply.
facilitate
- iThe new tunnel facilitated trade across a range that had blocked it for centuries.
- iiA good moderator facilitates the discussion without steering its conclusions.
- iiiThe app facilitates communication between patients and their doctors.
They are opposites, but inhibit is milder than 'prevent' — an inhibited process still happens, just less. Inhibit pairs with 'X from doing Y' ('inhibit students from speaking'); facilitate takes a plain object ('facilitate trade').
