Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
flāgĭtātĭo, ōnis, f. [flagito], an earnest request or demand, importunity (rare but class.): nolui deesse ne tacitae quidem flagitationi tuae, * Cic. Top. 1, 5: uxorum flagitatione revocantur, Just. 2, 4.
In plur.: crebrae populi flagitationes, Tac. A. 13, 50.
