The phrase "more ill at ease" is a combination of the words "more" and "ill at ease".
The word "ill" originates from the Old English word "ylle", which means evil, wicked, or bad. Over time, it came to be associated with being sick or unwell, both physically and mentally.
The term "at ease" comes from the Middle English word "ese", meaning comfort or contentment. It evolved from the Old French word "aise".
When "ill" and "at ease" are combined, the phrase "ill at ease" refers to a state of discomfort, unease, or feeling uneasy in a particular situation or environment.
Therefore, when the word "more" is added to "ill at ease", it simply intensifies the level of discomfort or unease being described.
