If a word conforms to a special rule, I call it an Ordered Word™.
Use the examples below to find the rule.
$$ % set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ Ordered }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\ \def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Words }^™\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2017.02.04}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{CAT} & \text{DOG}\\\hline \text{BACK} & \text{FRONT}\\\hline \text{NO} & \text{YES}\\\hline \text{BEST} & \text{WORST}\\\hline \text{DEMON} & \text{ANGEL}\\\hline \text{FELL} & \text{ROSE}\\\hline \text{TEA} & \text{COFFEE}\\\hline \text{ONE} & \text{TWO}\\\hline \text{WOOF} & \text{MEOW}\\\hline \text{LIE} & \text{TRUTH}\\\hline \end{array}$$
