Could such be a later Latin word? I can’t find it as a certain part of speech. What does it mean?
Cheers! 
Nor I. Is it maybe an OCR error for “fracti”, the participle “fractus -a -um” from the verb “frango”? What’s the context,—the whole sentence in which it appears? Or written in place of “frētum -a -um” (“relying on”)?
P.S. I bet you it’s written for “fracti”. Searching on the internet that’s what I find.
Nec ego. Estne fortassìs erratum cognitionis characterum opticae pro “fracti” participio “frango” verbi? Da sententiam integram in quâ invenitur. Estne “frētum” adjectivi loco scriptum?
Post scriptum. Ausim deponere tecum, pro “fracti” scriptum est. Sic video in interrete quaerens.
