If a word conforms to a special rule, I call it a Peachy Word™.
Use the list of examples below to find out what this rule is.
$$\begin{array}{|c|c|} \hline \textbf{Peachy Words™}&\textbf{Not Peachy Words™}\\ \hline \text{GROAN}&\text{GRUNT}\\ \hline \text{BYE}&\text{FAREWELL}\\ \hline \text{TONES}&\text{RINGING}\\ \hline \text{MONKEYS}&\text{APES}\\ \hline \text{SEVEN}&\text{EIGHT}\\ \hline \text{ASH}&\text{SMOKE}\\ \hline \text{ROWAN}&\text{WILLOW}\\ \hline \text{HALLO*}&\text{GREETINGS}\\ \hline \text{MOTOR*}&\text{CYCLE}\\ \hline \text{NOTHING}&\text{NOUGHT}\\ \hline \text{CASTS}&\text{THROWS}\\ \hline \text{FARTING}&\text{BURPING}\\ \hline \text{HOUSE*}&\text{HOME}\\ \hline \end{array} $$
($^*$ denotes an Extra Peachy Word™.)
Text-only version for analysis:
GROAN GRUNT BYE FAREWELL TONES RINGING MONKEYS APES SEVEN EIGHT ASH SMOKE ROWAN WILLOW HALLO* GREETINGS MOTOR* CYCLE NOTHING NOUGHT CASTS THROWS FARTING BURPING HOUSE* HOME
FARTING
was not extra Peachy. FYI there is also one possibly Peachy Word™ in the Not Peachy Word™ list (CYCLE
), although it is uses a spelling variant of a fairly localised word. $\endgroup$
