مَآ : Relative Pronoun: masculine meaning that, which, who; and when referring to more than one place, thing or idea it denotes whatever, whichever, whomever.

A relative pronoun in Arabic is called: الاسم الموصول and it is followed by a sentence, nominal or verbal, as its relative clause called: صلة الموصول.  Relative clause has a pronoun termed [الْعَائِدُ] that links back to relative pronoun.

Relative pronouns are as they are in whatever role they are used (subject of nominal sentence or verb; predicate or object of verb or preposition, second noun of possessive phrase in the sentence; meaning their case ending remains the same.

Relative Pronouns (ضَمائرَ الوصل) are used as conjunctions, meaning "that, which, who, whom, whichever, whatever, whomever". They serve the purpose of joining nouns, pronouns or verbs to other nouns or verbs. They are used to introduce subordinate adjectival clauses and therefore create complex sentences. The choice of such pronouns depends on the antecedent's number and gender.

""A noun of the connected [الاسم الموصول]". Being nouns, relative pronouns have the characteristics of nouns, namely gender, number, and grammatical case. Relative pronouns are always definite words.

Its usage has two specific rules: it agrees with the antecedent in gender, number and case, and it is used only if the antecedent is definite. If the antecedent is indefinite, no relative pronoun is used. The former is called jumlat sila (conjunctive sentence) while the latter is called jumlat sifa (descriptive sentence).

Referring to a place, thing or idea: Which, That
When using relative pronouns for places, things or ideas, rather than determining case, the writer must decide whether the information in the dependent clause is essential to the meaning of the independent clause or simply additional information.

When information is critical to the understanding of the main clause, use That as the appropriate relative pronoun and do not set the information off by commas.

When information is not critical to the understanding of the main clause, use "Which" as the appropriate relative pronoun and set the information off by commas.

When referring to more than one place, thing or idea use these relative pronouns: Whatever, Whichever
