The rule of initial o deletion is so rigorous that even loan words with initial o are subject to it.
55  oja ‘teacher [a loan word from Meitei]’     ni1 ja2 ‘your [sg.]1 teacher2           b [i]         56 osi ‘dog’
osi + khelo ą silo ‘male dog’ osi + okrü ą [o]sikrü ‘productive female dog ; mother dog’ osi + kheni ą sini ‘unproductive female dog’
While the forms osi okrü and osi khemi are not possible, osi khelo is. In other words, the sandhi rule of o- deletion is optional in the case of osi khelo.
57. ovo ‘pig’         ovo + khelo ą volo ‘male pig’   ovo + okrü ą vokrü ‘productive female pig ;     mother pig’         ovo + kheni ą voni ‘unproductive female pig’       58.  okhe ‘tiger’           okhe + khelo ą khelo ‘male tiger’   okhe + okrü ą khekrü ‘productive female tiger ;     mother tiger’         okhe + kheni ą kheni ‘unproductive female tiger’       59. otu ‘domestic ruminant bovine ; ox’         otu + okrü ą tukrü ‘productive cow ; mother-cow’   otu + khelo ą tulo ‘unproductive cow’
There is, however, no deletion when the gender word marks male bovines because this particular gender word has no deletable prefix.
60. otu phodu ‘bull’   [male [bovine]]         61. oho ‘domestic fowl’   oho + okrü ą hokrü ‘productive hen ; mother-hen’   oho + dzü ą hodzü ‘cock’   oho + ve ą hove   ‘unproductive hen’
