Isimo se- Umbhobho wombhobho iyefana nohlamvu olukhulu lwesiNgisi (T), ngakho-ke lolu hlobo lombhobho lubizwa ngokuthi umbhobho we-T ngamafuphi.

Isici sombhobho we-T ukuthi sinesimo esifushane futhi singafakwa esikhaleni esincane.Umumo wesifutho ngokuvamile uyi-cylindrical eqondile, fan eyisicaba nesigaxa esigcwele.

Umbhobho we-T unezici zentengo yomkhiqizo ophansi, ukufakwa okulula, nobude obufushane obuphelele. Ingakwazi ukuzivumelanisa nezindawo ezahlukahlukene zokufaka. Impilo yenkonzo yayo ayihlukile kunemibhobho evamile. Sicela uzizwe ukhululekile ukuxhumana nathi ngemingcele yezobuchwepheshe kanye nezilinganiso zomkhiqizo eziphansi. .
