How long is the longest word in English that consists of only letters lack ascenders descenders and dots lower case?

The longest word in English that consists only of letters lacking ascenders, descenders, and dots in lowercase is "level".

Here's why:

* Ascenders: These are the parts of letters like "b," "d," "f," "h," "k," and "l" that extend above the main body of the letter.

* Descenders: These are the parts of letters like "g," "j," "p," "q," and "y" that extend below the main body of the letter.

* Dots: This refers to the dot over the lowercase "i" and "j".

The letters in "level" are all lowercase and have no ascenders, descenders, or dots.
