English has quite a lot of nouns that end in <ade>. For most of these the pronunciation is eɪd and the main stress is on the final syllable:
balustrade cavalcade colonnade lemonade palisade parade tirade
There are some exceptions. Marmalade is pronounced ˈmɑːməleɪd. Comrade is pronounced ˈkɒmreɪd. The word promenade is usually pronounced ˌprɒməˈnɑːd.
Thanks to Petr Rösel for:
accolade = ˈækəleɪd and charade = ʃəˈrɑːd or occasionally ʃəˈreɪd.
