word pūrvāpahāṇā are mentioned in a Gaṇa to Pāṇ. IV. 1. 4.
on account of the irregular formation of the feminine in ā,
for the affix of apahāna being ṭit (i. e. lyuṭ)--Kāśikā:
ṭinnipātanāt--the word ought to end in ī (ṅīp). In ac-
cordance with this view Mādhava explains both words in the
Dhātuvṛtti pūrvānparāṃśca jahāti--in adopting apparently the
reading parāpahāṇā mentioned also by the Gaṇaratnam. i. e.]
One (fem.) who or which leaves those who or which are be-
hind &c. (see apara). [But the Gaṇaratnam. proposes some other
queer meanings, viz. apahīyate'nayāsyāṃ vā (comp. Pāṇ. III. 3.
117.) . apahāṇā . pūrvasyāpahāṇā pūrvāpahāṇā (comp. Pāṇ. II.

parāpahāṇeti paṭhanti .., i. e. a. Tatpur. fem…by which (whom)
or in which (whom) something or some one subsequent is
left (i. e. similar to Mādhava's explanation); but the Gaṇar.
doubts of this meaning. b. Karmadh. fem. A subsequent
woman(?) who is abandoned; with a corresp. masc. ending
in a dental na. c. Bahuvr. fem…from which or whom
something subsequent has gone away; when apahāna is the
past partic. of hā ‘to go’ with apa. All these explanations
are probably only etymological and refer to some conven-
tional sense of the word which is not stated by the com-
mentators of Pāṇini.] Bhoja and the Kāśikā give the reading
aparāpahāyaṇā. E. apara and apahāna.
