Why do you have to add 'se' in 'se promener'?
Help please, I don't understand what 'se' means and why you have to put it before promener
"se" is a reflexive pronoun, like in English "herself." It is used with reflexive verbs (actions that are done to yourself). https://www.lawlessfrench.com/grammar/reflexive-verbs/
''se'' is put in front of some verbs to explain your are doing it to yourself.
in french, the verb for "to walk" is "marcher", but then "taking a walk" is "se promener"
"Je promène mon chien" is " I walk my dog" "Je me promène" is litterally "I walk myself"
"Il lave sa voiture" is "he washes his car" "Il se lave" is "He washes himself"
that's wrong; you'll either say "prendre une marche" which litterally means "taking a walk" or use the verb "se promener". they have the same meaning but I don't know if Duolingo would accept both
