Help for a tabfile's regex

Hi, I was searching a regex (perhaps for notepad++) that allow me this:

word1TABdefinition1definition1definition1definitio n1definition1
word7TABdefinition7definition7definition7
word8TABdefinition8definition8definition8definitio n8definition8
word9TAB(plural of word7 English)
word93TABdefinition93definition93definition93defin ition93definition93

It must become:

word1TABdefinition1definition1definition1definitio n1definition1
word7TABdefinition7definition7definition7
word8TABdefinition8definition8definition8definitio n8definition8
word9TAB(plural of word7 English) definition7definition7definition7
word93TABdefinition93definition93definition93defin ition93definition93

Thanks
