In the case you want to delete a word in a sentence, just create a small macro that removes the word.
But it will become difficult when you have word like, for example, "Theword" or "THEWORD" or "theword" .
Each of these word are different, but contains the same characters.
This little macro solves this problem.
Option Compare Text
Dim Cel As Range, Range As Range
Dim Word As String
Set Range = Range("B2:B20") '.
Word = "Theword"
Application.ScreenUpdating = False
For Each Cel In Range
If Cel Like "*" & Word & "*" Then
Cel = Replace(Cel, Word, "")
'To remove the double space that follows ..
Cel = Replace(Cel, " ", " ")
Application.ScreenUpdating = True
