Y for yantramu

Y for yantramu

yantramu means machine.
యంత్రము
యం=yam/yan
త్ర=tra
ము=mu
Remember, in telugu when two consonants come together as in tra=t+r+a or tri=t+r+i, the second consonant becomes a sign and the vowel sign corresponding to the second consonant is written on the first consonant.
త్రి  = త్ + ర్ + ఇ
tri  = t  +  r + i
Look the i sign is written on t rather than on the r which appears as a sign. The elongated u written below త(ta) is the sign/voththu for r.
So kri is written as క్రి

So mri is written as మ్రి
So pri is written as ప్రి
So for i is the comma like sign written on the top of the letter.
In cases where the tala kattu is written joined up to the letter, the sign is also joined up as in the case of vi(వి) and in case of pi(పి as in pin) the sign is written disjointed.
