The word vahyaṃ is irregularly formed when the meaning of the word is an instrument of carrying.,
The word वह्य is derived from root वह 'to carry' and means 'a vehicle', i. e., that by which a thing is carried; as वह्यं शकटम्. When it does not mean a carriage, the root takes the affix ण्यत्; thus वाह्यः 'an ox'.,
