√ ṛj, ṛñj, arj, ‘direct, stretch, attain’

Pres. [7.] ṛñjate (3 p.). rv. , — [6.] ṛṅjáti -áte etc. rv. aa.  — [4.] ṛ́jyant, ṛjyate rv. ṛñjase (1s.) ṛṅjasāná rv. — [1.] árjati b.u.c. </span>
Perf. [ānarjus] ānṛjús av1.

Deriv.:

arjaka c. ṛjipyá v.+ ṛ́jīyas v.
-arija c. ṛjíśvan rv. ṛjú v.+

arjanīya c. ṛjīṣá rv. rájiṣṭha- rv.b.
-arjayitṛ c. ṛjūnas rv. rajīyas jb.
  -ṛñga rv. -rāji av.+

It seems impossible to divide these forms (generally distributed to two different roots) from one another. The root has three well-marked stages of development : ṛj or ṛñj in rv., arj in Brāh., and arjaya in the later language. Compare also √rāj, probably a derivative from it. With it is related, further, the anomalously formed stem irajya (irajyáti -te etc. RV., and irajyú rv. ), ‘direct, rule’.

√ 2 ṛj, ‘shine’

Inferable from the derivatives.:

árjuna v.+ -ṛjīká v. ṛ́jīti rv. ṛjrá rv. +
       



————————————————————————

√ ṛt, art, ‘pursue’

Aor. 5. artiḍhvam pb1.
Fut. artiṣye av1.
Deriv.:

árjuna v.+ -ṛjīká v. ṛ́jīti rv.
     

A very doubtful root ; ánvartiṣye and anvartitṛ́ apparent contractions for anu-vart; and Bö. amends artiḍhvam to arthi- (but??). But artana and artuka seem to show that the thing had assumed the value of a root.

√ ṛd, ard, ‘stir, dissolve’

Pres. 6. ṛdantu ā́rdan rv. — [1.] árdati etc. av.+ [— 7. ṛṇatti]

árdhya rv. -ṛdh vs. ṛ́ddhi av.+ -ardhayitṛ u.s.

√ ṛś, ‘harm’

Perhaps to be inferred from the derivatives:

-arśa rv.+ árśas vs.+ ṛ́kṣa v.+ ṛkṣī́kā av.b.
-arśani rv. arśasāná rv. ṛkśara v.

-árṣaṇa b. arṣṭṛ́ b. ṛ́ṣi v.+ ṛṣvá vb.
arṣaṇī́ av.   ṛṣú rv.  


Hardly calls for the usual division into two roots. Some of the derivatives doubtful
