In Arabic صديق

a friend: Sadeeq صديق
or: rafeeq رفيق
or: Sahheb صاحب
(someone you are friends with because you work together): Zameel زميل
friendship: Sadaqatun صداقة
the friend: aSSadeeq الصديق

SADEEQ is the masculine term. The plural is ASDIQAA'

SADEEQA is the feminine term. The plural is SADEEQAT.

The letter Q is variously pronounced, most commonly as a hard G (in the Persian Gulf region), or as a glottal stop (in Egypt and the Levant).

As Raghad mentioned above, another very common term for "friend" is SAHIB (the stress is on the first syllable). I grew up using this word more than SADEEQ.

Raghad's other term, RAFEEQ, is closer to "companion." It also is used for "comrade" in Marxist literature. In some regions, school children use the term for "classmate" or "playmate".

KHALEEL (meaning "close or intimate friend") is undeservedly neglected in contemporary usage.

As always, all the above terms have gender-specific and number-specific variations.
