I am learning in the car from CD's with no text book
Sometimes the words seem to roll into one another
For instance - telephoning the wrong hotel room was answered by - habitacion no acqui bocada (or vocado) - you have rung the wrong room?
Any ideas'
Might turn into quite a fun game..!
I'm guessing you heard "habitacion equivocada" wrong room
good luck! I feel your pain; I really depend on visuals too. Watching a film without Spanish subtitles is murder for me

You have the wrong room. "Habitación equivocado"
how about habitacion equibocada'
I guess, just a guess, that you heard an "n" plus a vocalic sound which you couldn't identify, but transcribed as oa: "habitacion no acqui bocada", in your transcription . That would accoount for the "no". Otherwise it makes no sense. As other members have said, it must be "habitación equivocada". I'm pretty sure.
My very favorite is, direct & indirect object pronouns in the same sentence.
We had a little exercise in class, this is one of the sentences.
I have already prepared it for you. (Comida) Ya se la he preparado.
Believe it or not I got it right, but that's writing it, speaking is something else.
We won't even talk about subjunctive.
Jeje. Object pronouns, not motley's favorite =D
Why would NO be in that sentence? equivocada takes care of it unless it's one of those %#$@&' pronouns.
I'm sure equivocar is reflexive, but that's me,te,se,nos.se.
lol, yup, I posted my first question yesterday, and I'm pretty much hooked and lined up with tons of questions

Thank you
Phonetically it fits with my hearing
"a key bocada" actually is
equivocada
Thanks - a result on first question - I am sure I shall be back

that would make more sense !
ha sonado la habitacion incorrecto - would be something like you have rung the wrong room
Your partial transcription 'habitacion no aqui....' might be something like 'there's nobody called that in this room '
Definitely 'room' (habitacion) and 'here' (aqui) and 'not' (no) are easy enough to pick up, so the rest may be a good guess
