I gave up on doing that - my vocabulary is terrible and I just want to contribute and have fun ;). All words being posted now are far beyond me.

###The instructions for this game are:###
1. Change just ONE letter and/or Rearrange the letters and form a new 4-letter word.
(Words should be found in a common English dictionary.)
(No proper names, titles, brand names, trademarks, contractions, abbreviations, combining forms (hyphenated words), or acronyms please.)
(All words should be found in at least two independent resources that corroborate the definition.)
The Challenge of this game is to post words that have not been used before (if possible).
To minimize repeats, Click the magnifying glass icon at the top right of the window. The search function is blazingly fast!
IMPORTANT!
Help keep the word train rolling! Before responding to the latest post, scroll back a post or two to be sure the latest word is valid. If it is not, just “Reply With Quote” to the last valid submission and skip the invalid one.
Game on!

sigh as was pointed out to me, that wouldn’t be a valid word in the chain.
Try #2 -
deif
OK, Try #3
lier - changed because apparently deil can’t be validated
Now it works (and you know who you are 
)
deil
Who? Me? ? Never!
