Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
stīpendĭor, ātus, 1, v. dep. n. [id.], to receive pay, to serve for pay (very rare): regi eorum peditum sexcenta M. stipendiantur, Plin. 6, 19, 22, § 68.
Transf.: (infantes Pontici) butyro stipendiati, serving for butter, getting butter for pay, i. e. for their maintenance, Tert. adv. Marc. 3, 13.
