Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

1. căchinno, āvi, ātum, 1, v. n. [like καχάζω or καγχάζω; Sanscr. kakk; and our titter, onomatop.], to laugh aloud, laugh immoderately.

  1. I. Lit. (class. but rare): famulae furtim cachinnant, Lucr. 4, 1176; 1, 919; 2, 976: ridere convivae; cachinnare ipse Apronius, Cic. Verr. 2, 3, 25, § 62; Suet. Vesp. 5; Aur. Vict. Epit. 28.
    With the acc. of that which one laughs at: exitum meum cachinnant, App. M. 3, p. 132, 25.
