I have a couple of questions.

Is this a correct way of saying I like to ride a bike in the summer? Do I need an article before été?

En été, j'aime faire du vélo.

Is l'opération male or female?

How do you say I like to visit different places in the holidays?

I'll send this to our French expert, SraJMcGin.

First sentence is perfect! No, no article with été here.

Handy hint: all words ending in -tion are feminine.

J'aime visiter des endoits différents pendant (during) les jours de fête. (in = dans, if you prefer)

Sra (aka Mme)

I'll "flag" this so I can come back later, in case you have other questions.

Let's break down your questions one by one:

1. Is this a correct way of saying "I like to ride a bike in the summer"? Do I need an article before été?

The sentence "En été, j'aime faire du vélo" is indeed a correct way of saying "I like to ride a bike in the summer" in French. In this sentence, "en été" means "in the summer," and "j'aime faire du vélo" means "I like to ride a bike."

Regarding the article before "été," in this specific sentence, you don't need to add an article before "été." However, if you want to say "in the summer of" or refer to a specific summer, you would use "l'été" with a definite article. For example, "J'ai visité la France pendant l'été de 2020" (I visited France during the summer of 2020).

2. Is "l'opération" male or female?

In French, nouns have grammatical gender, either masculine or feminine. The word "l'opération" is a feminine noun. However, there are some nouns that don't follow the regular gender patterns, so it's always best to consult a dictionary or rely on familiarizing yourself with the gender of the noun through exposure and practice.

3. How do you say "I like to visit different places in the holidays"?

To say "I like to visit different places in the holidays" in French, you can use the following sentence:

"J'aime visiter différents endroits pendant les vacances."

In this sentence, "J'aime" means "I like," "visiter" means "to visit," "différents" means "different," "endroits" means "places," and "les vacances" means "the holidays."
