Tamil meaning :Arabian jasmine, Jasminum sambac; some other varieties of jasmine
Malayalam :mulla
Malayalam meaning :Jasminum sambac, etc.
Kannada :molle
Kannada meaning :Jasminum multiflorum or pubescens
Notes :Irregular -u- in Tamil/Mal. (the Kannada variant is primary, as it is confirmed by Telugu). This might be due to contamination with *muḷ- 'thorn' (?) or *muḷ- 'sprout, shoot, germ' (?).
It is unclear if Kan., Tulu mōṇṭu have to be traced to a separate root *mōṇṭ-; if so, Tamil forms like moṭṭai, moṇṇai should probably be considered as descended from roots with weak clusters. Cf. also the following forms: Ta. moṇṭu refractoriness, unruliness, annoyance, worry; moṇṭi, moṇṭukkāran_ refractory man; Kannada moṇḍu, moṇḍutana stupid obstinacy, esp. in demanding or dunning. These forms are joined by B&E with *mur- 'rough, rude', but this is hardly possible.

Kannada derivates :musur_ to cover as flies, crows, etc., crowd together, cover, hide; n. cover, veil; musumbu cover, veil
Notes :Tamil muṭṭai, Mal. muṭṭa due to contamination with muttai 'lump' (at least, this is a far more probable explanation than setting up an extraordinary umlaut case before a voiceless consonant). Tamil muṇṭai unclear.
Tamil meaning :to roar, thunder, make loud noise, be noised abroad, be made public
Tamil derivates :muẓakku (muẓakki-) to sound, beat a sounding instrument; n. sound, noise; muẓakkam loud noise, as of thunder or drums, clamour, roar; muẓavu, muẓā drum, large loud-sounding drum; moẓi (-v-, -nt-) to say, speak; n. word, saying, language

Notes :The forms with -ō- have to be considered regular here. The forms with -ū- are due to contamination with *mūḍ- 'to cover', although the contamination had probably begun on the PDR level itself.
Tamil derivates :(?) māntu (mānti-) to eat, drink, experience, enjoy
Malayalam :mōkuka, (?) mōntuka
Malayalam meaning :to drink, sip
Malayalam derivates :mōyikka to give to sip; mōval a gulp
Notes :The root here is *mōg-, as evidenced by Tamil moci < *mōg-i-, and confirmed by external data. Therefore, Malayalam forms like mōyikka should be explained as due to a reinterpretation of the form mōkuka as *mō+k+uka. However, Mal. mōntuka, Tam. māntuka hardly belong here at all.
