Learn Arabic (Modern Standard): الخبر المأساوي جعل الرجل يتجمد من الذعر. - The tragic news made the man freeze from panic.

This is the causative construction using جعل. It takes a direct object, الرجل (the man), followed by a regular present tense verb, يتجمد (he freezes). Notice that while English uses the bare infinitive 'freeze', Arabic uses a fully conjugated verb that matches the object.

Why doesn't the second verb يتجمد need the particle أن (that/to) before it?

Verbs of causation like جعل take a bare present tense verb directly as their second complement. If you used أن, it would force the subjunctive case and is grammatically incorrect for this specific 'to make someone do something' structure. Here, يتجمد remains in the standard indicative case.

What case ending does الرجل take here?

It takes the accusative (fatha) ending, becoming الرجلَ (ar-rajula). Even though the man is the one doing the freezing, grammatically he is the direct object receiving the action of 'making' from the verb جعل.

The word for tragic, المأساوي, ends with a nisba suffix. What noun is it derived from?

It is derived from the noun مأساة (ma'sāh), which means 'tragedy'. When adding the nisba (relational) suffix ـي (iyy) to turn it into an adjective, the ending ة (taa marbuta) is replaced with a و (waw) to bridge the vowel sounds, creating مأساوي (ma'sāwiyy).
