Misalai

“A tilde over an r indicates that it is rolled/trilled, not flapped: r̃, R̃.”

“The symbol r̃ (with the tilde diacritic) differentiates the alveolar tap/roll from the retroflex native flap r [ɽ], a phonemic contrast which is not marked in Hausa orthography (§16).”

“Hausa has two partially contrastive R sounds: a retroflex flap and a roll/tap. These are not distinguished in the standard orthography nor in Hausa written in Arabic script (termed ajami). In this dictionary (as well as in the companion English–Hausa Dicitonary and The Hausa Language), the difference between the two R’s is overtly marked as a pronunciation guide. (The distinction is, however, ignored for the purposes of alphabetization.) The flap R, e.g., rānā “sun”, is transcribed with the ordinary r symbol. The roll/tap R, e.g., r̃ahā̀ “pleasant chatting”, is written as r̃ (i.e., r with a tilde).”

“A tilde over an r indicates that it is rolled/trilled, not flapped: r̃, R̃.”
