budged

  1. He budged in his seat.
  2. He moved slightly in his seat.
  3. He moved over a little in his seat.
  4. He moved a little over his seat.
    Are all these sentences OK?
    Do they all mean the same?
    Thanks.

1 is not the correct usage. You might say, “He budged up to make room on his seat” but just saying ‘he budged’ is not right. The only kind of example I can think of where ‘budge’ is naturally used alone (without a following preposition of some kind) is in the negative like this:
Sit there and don’t budge!
Don’t budge until I come back.

  1. does not have the same meaning as ‘budge’. It is not clear enough regarding the movement made to be able to use ‘budge’.

  2. ‘moved over a little’ can be interchanged with ‘budged over’.

  3. is incorrect. The word order is wrong. Use 3.

Beeesneees,
For ‘He moved over a little in his seat.’ can I say :

  1. He budged over in his seat.
    OR
  2. He budged over his seat.
    Which is correct?
    Thanks.
  1. is correct.
