The Full Stop by Solomon Osuokam Ogbeh

The full stop (or period, as it is known in American English) is a fundamental punctuation mark in English. Its primary function is to signal the end of a sentence. Understanding how and when to use the full stop correctly is essential for clear and effective writing.

Functions of the Full Stop

1. Ending a Declarative Sentence

The most common use of the full stop is to mark the end of a declarative sentence—a statement that conveys information or expresses an idea. For instance:

• Aisha went to the market yesterday.
• The sun rises in the east.

In these examples, the full stop indicates that the thought is complete.

2. Ending an Imperative Sentence

Imperative sentences give commands or instructions. A full stop is used at the end of such sentences when they are polite requests. For example:

• Please submit your assignments by Friday.
• Turn off the lights when you leave the room.

Here, the full stop shows that the command or request has been made.

3. Ending Indirect Questions

When questions are indirect, they are usually statements that contain a question within them. The full stop is used at the end of these sentences. For instance:

• I wonder where Chinedu went yesterday.
• Can you tell me if the bus has arrived?

These sentences report on a question rather than asking it directly.

4. Abbreviations

Full stops are also used in abbreviations. They signal the omission of letters or parts of words. For example:

• Dr. for Doctor
• U.S. for United States

It’s important to note that some abbreviations, particularly those involving letters rather than words, may not use full stops in modern usage.

Detailed Usage Rules

1. Single Full Stop at Sentence End

Every complete sentence ends with a single full stop. Ensure that a full stop is not misplaced or omitted, as it can lead to confusion or run-on sentences. For example:

• Incorrect: The students are studying they have an exam tomorrow.
• Correct: The students are studying. They have an exam tomorrow.
1. Avoid Overuse

Refrain from using multiple full stops after a sentence, as this is considered incorrect. For example:

• Incorrect: The meeting starts at 3:00 p.m...
• Correct: The meeting starts at 3:00 p.m.

Multiple full stops can be used in informal writing to indicate a pause or trailing thought but should be avoided in formal writing.

3. Full Stops with Quotation Marks \

When a sentence ends with a quotation, the full stop is placed inside the quotation marks. For example:

• “The weather is lovely today,” said Ngozi.
• “I will attend the meeting,” added Chukwudi.

This rule ensures that the full stop is part of the quoted material.

4. Full Stops in Lists

When using bullet points or numbered lists, a full stop is not always necessary unless each item is a complete sentence. For example:

• The following items are required:
• A pen
• A notebook
• An eraser

However, if the list items are complete sentences, they should end with a full stop:

• The following instructions must be followed:
• Please submit your essay by 5 p.m.
• Ensure all sections are completed.
• Double-check for spelling errors.

Examples in Context

1. Academic Writing

In academic writing, precise use of full stops is crucial. For example:

• Nigerian students should focus on their studies.
• The government is planning new educational reforms.

These sentences are straightforward statements that benefit from clear full stop usage to enhance readability and comprehension.

2. Creative Writing

Creative writing allows for a bit more flexibility, but the full stop remains a key punctuation mark. For example:

• Emeka looked out the window. He saw the rain falling softly on the ground. He felt a sense of peace wash over him.

Each sentence ends with a full stop, helping to pace the narrative and separate ideas.

3. Formal Communication

In formal communication such as letters or official documents, the full stop is essential for clarity. For example:

• Dear Ms. Afolabi,
• I am writing to confirm your appointment for the interview on Monday.
• Sincerely,
• Tunde Bakare

Each sentence is clearly marked with a full stop, ensuring the message is conveyed accurately.

Common Mistakes and How to Avoid Them

1. Run-on Sentences

A common mistake is failing to use a full stop to separate two independent clauses. For example:

• Incorrect: Moses is going to the shop he needs to buy groceries.
• Correct: Moses is going to the shop. He needs to buy groceries.
1. Incorrect Placement

Placing a full stop inappropriately within a sentence can lead to confusion. For example:

• Incorrect: The teacher said, “Please submit your homework by Friday.”.
• Correct: The teacher said, “Please submit your homework by Friday.”
2. Omitting Full Stops in Abbreviations

Sometimes full stops are omitted in modern abbreviations, but this should be consistent. For example:

• The U.K. is different from the U.S.

Exercise

1. Complete the following sentences using full stops where necessary:
• The rain stopped. The sun began to shine again.
• The students were excited about the upcoming holiday.
• Please remember to bring your textbooks to class.
2. Identify and correct the misuse of full stops in the following sentences:
• The principal announced the new school rules. The students will need to adhere to them strictly.
• Tolu asked if the project was due on Monday
3. Rewrite the following sentences correctly, adding full stops where needed:
• Mariam visited the museum She took many photos of the exhibits
• The football match was postponed because of the heavy rain

By mastering the use of full stops, students can improve their writing clarity and effectiveness. Practising these rules and recognising common errors will enhance both written communication and overall language proficiency.
