If
IT*IRK+KLM=TRUE
and
7844$ is a common English word
and
in the above coding distinct digits are represented by distinct letters

then

What letters might be represented by the dollar sign ($)?

Rem1: No acronyms, plurals, proper names, esoteric words.

Rem2: Although there are numerous solutions of the alphametic equation, there exist quite a few candidates for ($) (i.e. the last letter of the common word), with a certain letter (which?) dominating the set.

(In reply to Candidates by tomarken)

I am not sure that the 7,8,4 appearance generates only those two - I remember TUMMY and TELLS and do not want at this stage tell you more about this case,

However if you allow even a single letter out of the equation you

will get SORRY, WORRY,  TWEED   and some others.

It is a  D4  puzzle and it demands such a research  as  to be sure that the majority of the letters fittung "$" is  Y, S, O or other.

I believe those hints are sufficient at the stage you are now. 

Rem: removed redundant samples and added TWEED .
