Question 1

What is the difference between make, let, and allow?

Accepted Answer

The difference is about force versus permission. "Make" means to force someone — they have no choice: "My boss made me work overtime" (I had to do it). "Let" means to permit someone — you give them the freedom to act: "My boss let me leave early" (I was free to go). "Allow" is a more formal version of "let" — it also means to give permission: "The company allows employees to take breaks" (formal rule). The grammar is different too: "make" and "let" use the base verb (no "to"): "make me go," "let me go." "Allow" uses "to": "allow me to go." Choosing between "let" and "allow" depends on formality — "let" is everyday, "allow" is official.

Question 2

Why does "make" need "to" in the passive but not in the active?

Accepted Answer

In the active voice, "make" uses the bare infinitive: "She made him wait" (no "to"). In the passive voice, "make" changes to the full infinitive with "to": "He was made to wait." This is a fixed grammar rule in English — when the sentence is restructured into the passive, the bare infinitive becomes a full infinitive. The same thing happens with verbs of perception: "I saw her leave" (active, no "to") becomes "She was seen to leave" (passive, with "to"). "Let" does not have a common passive form at all — instead, English uses "be allowed to": "I was allowed to leave" (not "I was let to leave"). This active-passive shift is a commonly tested grammar point at B1 and B2 level.

Question 3

Can I use "let" and "allow" in the same way?

Accepted Answer

"Let" and "allow" both express permission, but they differ in formality and grammar. "Let" is informal and uses the bare infinitive: "Let me help you" and "She let them stay." "Allow" is more formal and uses "to" + infinitive: "Allow me to help you" and "She allowed them to stay." In everyday conversation, "let" is much more natural — "Allow me to introduce myself" sounds formal or old-fashioned. In written rules, regulations, and official contexts, "allow" is preferred: "Passengers are not allowed to stand in the aisle." An important difference: "let" has no standard passive form — use "be allowed to" instead: "I was allowed to go early." The only common exception is the fixed expression "let go" meaning dismissed: "She was let go last month."
