anya mātṛ ja

 The phrase anya mātṛ ja means “born of another mother,” essentially referring to a step‑sibling or half‑sibling depending on context.

What the words mean

• anya — “other, another”
• mātṛ — “mother” (stem form of mātā)
• ja — “born, produced, arising from”

Together, the compound anya‑mātṛ‑ja literally means “one born of a different mother.”

How the compound works

This is a tatpuruṣa compound (determinative compound):

• anya qualifies mātṛ → “other mother”
• ja qualifies the whole → “born from an other mother”

Possible interpretations

Depending on context, it can refer to:

• A half‑brother or half‑sister (same father, different mother)
• A step‑sibling (in broader or looser usage)
• Someone unrelated but treated like a sibling, in poetic or metaphorical Sanskrit

Related Sanskrit terms

• sapatna / sapatnī‑ja — born of a co‑wife (classical term for half‑siblings)
• sahodara — “born of the same womb,” i.e., full sibling
• mātṛ‑sahodara — same mother
• pitṛ‑sahodara — same father

Notes on usage

• The phrase anya mātṛ ja is grammatically correct but not the most common classical expression; traditional Sanskrit texts more often use sapatna‑ja or sapatnī‑ja.
• In modern Sanskritized usage, however, the literal compound is understandable and acceptable.

If you want a more idiomatic classical term

A more traditional way to say “born of another mother” would be:

• sapatnī‑jaḥ (masc.) / sapatnī‑jā (fem.) — “child of a co‑wife”
