Understanding the Correct Use of Linking Words for 13-Year-Old Students

The sentence you provided is: 'I would definitely go there again if Only when it's not busy.'

Let's analyze the linking words used here:

• 'if' is used to introduce a condition — it means 'on the condition that.' For example: 'I will go if it doesn't rain.'
• 'only when' means something will happen exclusively at the time that another event happens. For example: 'I go out only when it's sunny.'

In your sentence, 'if Only when it's not busy' combines two conditional phrases unnecessarily. Both 'if' and 'only when' are linking words that introduce conditions, but using them together back-to-back is incorrect.

Correct ways to write the sentence:

• Using if: 'I would definitely go there again if it's not busy.'
• Using only when: 'I would definitely go there again only when it's not busy.'

Both sentences are correct, but they slightly differ in emphasis. Using if suggests a possibility, and using only when implies the action happens exclusively at that time.

Summary: You should choose either if or only when, but not both together.
