Why do we have to use هذا if أسد already has the ال in front (ألاساد)?

[Wiebke740885]

The lion vs. this lion

الاسد - هذا الاسد

[iwsfutcmd]

Because it's (semantically) definite ("this lion" is a specific lion, not any old lion). Any noun used with "this" or "that" is implicitly definite. In English, that means you don't need to use the word "the" because it's essentially redundant. However, in Arabic, "ال" always has to be present if the noun is semantically definite.

(Note that if you said "هذا أسد" it would mean "this is a lion")

In English, if you use "this" or "that", it takes the place of "the". In Arabic, both have to be used at the same time.

[EvemarieMo]

what is the difference? (between "this" and "that" when only one is used)
