Learn Hardcore Arabic (Levantine): الصبح لقيت البطانية عالارض، والمخدة بعدا على السرير. - In the morning I found the blanket on the floor, and the pillow was still on the bed.

In Levantine Arabic, time expressions like الصبح, بالليل, اليوم, بكرا often work as adverbs without needing a separate word for in. So:

الصبح = in the morning / this morning

You could think of it as a natural time expression, not a full noun phrase that needs a preposition in English.

What does لقيت mean exactly?

لقيت means I found.

It comes from the verb لقي / يلاقي or لاقى / يلاقي in Levantine, meaning to find or sometimes to meet/run into, depending on context.

Here:

لقيت البطانية عالأرض = I found the blanket on the floor

The -ت ending shows I in the past tense.

Why does البطانية have الـ? Is it a blanket or the blanket?

البطانية literally means the blanket.

In Arabic, the definite article الـ is used much more naturally than English the in many everyday situations, especially when talking about familiar household items. So even if English might say in some contexts, Arabic often says if the item is understood from the situation.
