Which sentence sounds better?

*A 13 year old girl needs at least 1 hr. or exercise each day.

*A 13 year old female needs at least 1 hr. of exercise each day.

*A 13 year old female girl needs at least 1 hr. of exercise each day.

Please Help!!
Thanks!!

*A 13 year old girl needs at least 1 hr. of exercise each day.

You certainly don't need "female girl" in one sentence; it's redundant.

the second one seems good to me, definetely not the last one

Sorry, the 1st one IS better

I would go with the first sentence. The word "female" isn't used that much in informal language and since the word "girl" already implies that the person is of the female sex, sentence nr. 3 has a word too many.

Thanks

To determine which sentence sounds better, let's analyze each sentence and its grammar:

1. "A 13 year old girl needs at least 1 hr. of exercise each day."

This sentence is grammatically correct and conveys the intended meaning. It uses the phrase "13 year old girl" to describe the subject and states that she needs at least 1 hour of exercise each day.

2. "A 13 year old female needs at least 1 hr. of exercise each day."

This sentence is also grammatically correct and conveys the same meaning. It replaces the word "girl" with "female" to provide a more general term, but still maintains the same context.

3. "A 13 year old female girl needs at least 1 hr. of exercise each day."

This sentence is grammatically incorrect and sounds redundant. It combines the words "female" and "girl," which makes the sentence repetitive and unnecessary.

Overall, both sentences 1 and 2 are correct and convey the same meaning. It ultimately depends on personal preference whether you choose to use "girl" or "female" in the sentence.
