Questions & Answers about אולי השלט על השולחן; תבדקי אם הכפתור האדום עובד.
In Hebrew, the verb to be is usually omitted in the present tense. So השלט על השולחן literally looks like the remote on the table, but it means the remote is on the table.
This is very normal Hebrew grammar, not an incomplete sentence.
אולי means maybe or perhaps. It often comes at the beginning of the clause, just like English maybe:
אולי השלט על השולחן = Maybe the remote is on the table
It can appear in other positions too, but sentence-initial position is very common and natural.
Yes. שלט can mean remote control or sign, depending on context.
Here, it means the remote. The prefix ה־ is the definite article, so:
שלט = a remote / sign
השלט = the remote / the sign
Context tells you which meaning is intended.
