A verb appearing as ᴱQ. toko- in the Qenya Lexicon of the 1910s under the early root ᴱ√TOKO with various meanings: “feel with the hand, handle; appraise, tax, assess, assay; try, test, essay, endeavour” (QL/94).
Neo-Quenya: I would retain ᴺQ. toc- for purposes of Neo-Quenya but only for the sense “appraise, tax, assess, assay”. For “handle” I would use mahta-, and for “try” I would use nev- or ric-.
