Agreement when using etre for the past tense? If you have a masculine or singular subejct, but your DO is feminine ro plural, do you make agreement?

Hi Lalongi,

Il a monté la Tour Eiffel en escalier --- Il l'a montée en escalier

Note the use of 'avoir' with 'monter quelque chose'.

I prefer to use the verb 'escalader' here :

Le cascadeur a escaladé la Tour Eiffel à mains nues = The Stunt man climbed the Eiffel Tower with bare hands

So it will be also -"Il l'a escaladée"

Hope this helps!
