What does lamma mean in Arabic?

"Lamma" (لما) in Arabic means "when" or "whenever". It is a conjunction that introduces a subordinate clause that expresses the time or condition for an action or event.

Here are some examples:

* لما أَشْتَرىٰ كِتَابًا جَدِيدًا، أَقْرَؤُهُ فَوْرًا. (Lamma ashtaree kitabaa jadeedan, aqra'uhu fowran.) - When I buy a new book, I read it immediately.

* لما أَسْتَحِقُّهُ، أَحْصُلُ عَلَيْهِ. (Lamma astahiqquhu, ahssulu 'alayhi.) - Whenever I deserve it, I get it.

It is important to note that "lammā" is often used in conjunction with other conjunctions such as "idhā" (if), "ḥattā" (until), and "ḥīnā" (when).

For example:

* لما أُرِيدُ أَنْ أَسْفِرَ، أَسْأَلُ أَصْدِقَائِيَ عَنْ تَجَارِبِهِمْ. (Lamma uriidu an asfira, as'alu asdiqa'iya 'an tajaribihihm.) - When I want to travel, I ask my friends about their experiences.

In summary, "lammā" is a versatile Arabic conjunction that can be used to express different temporal and conditional relationships in a sentence.
