Question

The word indicates a sound produced when a person feels relieved. If
the First letter is changed with ‘H’ the first four letters would mean
something vertical.

Answer 1

The answer is HIGH.

Explanation:

• The sound that is made when a person is relived is spelled as "sigh".

• So when we replace the first letter of "sigh", that is "s", with "h", as instructed in the statement we get, "high".

• High means something of great vertical extent.

• It is usually used to define things that are great in height or the things that are tall.
