Choose the one-word substitute that means "to expel someone from a property, especially with the support of the law".

Introduction / Context:
Legal and social vocabulary often appears in English comprehension and usage questions. The phrase expel someone from a property, especially with the support of the law, describes a formal process used by landlords, courts, or authorities. There is a specific verb in English that captures this meaning, and knowing it helps in understanding news reports, legal documents, and exam passages related to tenancy and property disputes.

Given Data / Assumptions:

• The definition focuses on removal from property.
• The action is supported by law or legal procedure.
• Four words are given as options, some of which are adjectives describing friendly behaviour.
• We are to find the verb that fits this legal context.

Concept / Approach:
The verb evict is used when a landlord or authority removes a person from a house, flat, shop, or land through a legal process. It is different from casual words like throw out because it usually involves a notice, a court order, or some official action. The other words listed are adjectives that describe warm and friendly behaviour, which do not match the legal action described in the definition.

Step-by-Step Solution:
Step 1: Focus on the core idea expel someone from a property. Step 2: Add the extra detail especially with the support of the law, which points to a formal process. Step 3: Recall the standard legal term evict, often seen in phrases like evict a tenant. Step 4: Check the parts of speech of the options and select the verb that fits the sentence. Step 5: Confirm that evict matches both the meaning and grammatical form.

Verification / Alternative check:
Consider a sentence such as The landlord decided to evict the tenant for not paying rent. Here, evict clearly means to legally force someone to leave a property. Substituting the other options does not work: The landlord decided to genial or cordial or convivial makes no sense. This direct substitution check supports the choice of evict as the correct one word substitute.

Why Other Options Are Wrong:
Genial means friendly and cheerful and usually describes a person or atmosphere, not a legal action.

Cordial also means warm and friendly, especially in social interactions or relationships between people or countries.

Convivial refers to a lively, enjoyable, and friendly atmosphere, often at social gatherings, and has no relation to property or eviction.

Common Pitfalls:
Students sometimes focus only on one part of the definition, such as expel someone, and may think of general words like remove or drive out. However, the key detail is especially with the support of the law, which points to a formal property related action. Associating the phrase evict a tenant with property law will help you remember this meaning accurately for future questions.

Final Answer:
The correct one word substitute is Evict.
