Lesser or Lessor – Which Is Correct?

Have you ever written a sentence and hesitated at lesser or lessor? You’re not alone. These two words look almost the same and even sound very similar, but they mean completely different things. If you pick the wrong one, you might confuse your reader — or worse, appear careless in a legal, academic, or business context. In this article you’ll learn exactly what each word means, when to use it, how to remember the difference, and how to avoid common mistakes. By the end you’ll feel confident choosing the right word every time.

The Confusion Between “lesser” and “lessor”

The reason people mix up lesser and lessor comes down to spelling and pronunciation. Both begin with “less-” and end with an “-er” sound. But despite their visual similarity, they belong to totally different parts of speech and contexts. According to standard dictionaries:

• lesser is an adjective (smaller in size or importance)
• lessor is a noun (someone who grants a lease) 

Here’s a quick comparison table to make it clearer:

Because of the mix-up potential, it’s important to understand each word separately — starting with “lesser”.

What Does “lesser” Mean?

When you use the word lesser, you’re describing something as being smaller, lesser, or of a lower degree than something else. It often works in comparisons or evaluations.

Definition & function

lesser = of smaller size, amount or importance.
It functions as an adjective (modifies a noun) or in idiomatic expressions (e.g., “to a lesser extent”).

Common contexts & examples

Here are some sample sentences:

• “She accepted the lesser-known award.”
• “Among the two options, this seems the lesser risk.”
• “In Paris, and to a lesser extent other cities…”

It also appears in idioms like:

“the lesser of two evils” — meaning you pick the option that is less bad.

Practical usage tips

• Use lesser when comparing magnitude, importance or degree.
• Avoid using lesser when you’re talking about someone who leases property — that context calls for lessor.
• Double check the noun you’re modifying: if it’s about size/importance, lesser fits; if it’s about leasing, then lessor is correct.

What Does “lessor” Mean?

Switching gears — lessor belongs in the world of contracts, leases, property, business. It has a very specific meaning.

Definition & role

A lessor is a person or entity who grants the right to use an asset (property, equipment, real estate) through a lease. The person leasing the asset is the lessee.

Core responsibilities

In a typical lease agreement:

• The lessor owns the asset (e.g., building, car, equipment).
• The lessor grants use of the asset to the lessee in exchange for payments.
• The lessor may remain responsible for certain major maintenance or structural repairs (depending on lease type).

Example sentences

• “The lessor required a security deposit before the tenant moved in.”
• “In the equipment lease, the lessor will own the machine when the term ends.”

Important note

Don’t confuse lessor (leasing party) with lessee (the party using the asset). These are linked, but distinct roles.

Key Differences Between “lesser” and “lessor”

Understanding each word independently helps — but the real assurance comes when you can see how they differ side-by-side.

In summary

• Use lesser when you’re talking about smaller or less important.
• Use lessor when you’re talking about someone who leases something.

How to Remember the Difference

Let’s keep this simple with memory tricks you’ll actually remember:

• Lessor = Landlord → Both start with “L”.
• Lesser = Smaller → “Lesser” ends with “-er”, and “smaller” also ends with “-er”.
• Quick question before you write: Am I referring to someone who leases property? → use lessor. Am I referring to something being smaller or less significant? → use lesser.

Another way:

• If the sentence has lease, think lessor.
• If the sentence has less or smaller, think lesser.

These little mental shortcuts can help your brain pick the right form automatically.

Common Mistakes and How to Avoid Them

Even native speakers slip up. Here are the pitfalls and how you can sidestep them.

Mistakes people make

• “The lesser signed the contract.” ❌ (should be lessor)
• “We chose the lessor evil.” ❌ (should be lesser)
• Mixing meaning because of similar pronunciation.

How to check your own writing

• After you type the sentence, ask: Am I talking about someone leasing property (noun)? → then lessor.
• If you’re talking about magnitude, degree or importance, then lesser.
• Read the sentence out loud. If it sounds odd, change it.
• Use dictionaries or grammar tools for final proofing. Both lesser and lessor have clear definitions: see

Example corrections

• ❌ “The lesser owns that building and collects rent.”
  ✅ “The lessor owns the building and collects rent.”
• ❌ “By using the lessor-known method he saved time.”
  ✅ “By using the lesser-known method he saved time.”
