This is normally only a problem when conversing with monolinguals. Almost anyone who has expended the immense energy required to learn a second language will understand that language ability and intelligence are completely separate.
That being said, it is a shitty feeling that I have experienced many times.
France: If English is the second most common language, then as soon as you leave Paris or a really touristy spot, you’re fucked.
“Prolly” is how I pronounce it in speech, especially in the middle of a sentence.
I feel like one of the hardest things to master for non-native speakers, especially those who speak Romance languages, is the pronunciation of consonants that occur in the middle of phrases. It’s not a hard and fast rule, and depends on the speaker, but those said middle consonants are often very understated, especially in fast speech. I can always tell a Spanish or French native speaker because they would pronounce it: pro-Ba-BLEE, with the clear, distinct, staccato-like intonation of their mother tongues.
How are you trying to pronounce it? At least in my accent, the “ch” is just pronounced like a “k”…
