Taking yesterday's example of POINT:I feel this makes more sense. Easier to guess vowels. But more choice around the consonants?
If you work out that it contains an O and an I then you're almost there.
There's not many words which will fit that could start or end with O/I so you know those letters are likely to be in the middle and they're likely to be together in that order - OI
Then you just need to look at whatever other letters you've ruled out and think about the possible solutions. There's probably only 3-4 options at most for the word.
