Asking for Help Reading a Sign

You see a sign or notice you can't understand and ask someone to explain it.

You
Disculpe, ¿qué dice ahí en ese letrero? No puedo leerlo bien.
dees-KOOL-peh, keh DEE-seh ah-EE en EH-seh leh-TREH-roh? noh PWEH-doh leh-EHR-loh byehn.
Excuse me, what does it say there on that sign? I can't read it well.
'Letrero' is the common word for a posted sign or notice. 'Señal' is used more for traffic or road signs.
Local
Dice 'Prohibido el paso, solo personal autorizado'.
DEE-seh proh-ee-BEE-doh ehl PAH-soh, SOH-loh pehr-soh-NAHL ow-toh-ree-SAH-doh.
It says 'No entry, authorized personnel only'.
You
Ah, ¿qué significa 'prohibido el paso'?
ah, keh seeg-NEE-fee-kah proh-ee-BEE-doh ehl PAH-soh?
Ah, what does 'prohibido el paso' mean?
'Prohibido' means 'prohibited' or 'forbidden' — you'll see this word on many signs: 'Prohibido fumar' (No smoking), 'Prohibido estacionar' (No parking).
Local
Significa que no puede entrar por ahí. Tiene que ir por la otra entrada.
seeg-NEE-fee-kah keh noh PWEH-deh ehn-TRAR por ah-EE. TYEH-neh keh eer por lah OH-trah ehn-TRAH-dah.
It means you can't go in that way. You have to go through the other entrance.
