In the spirit of the What is a Word™/Phrase™ series started by JLee, a special brand of Phrase™ and Word™ puzzles.
Template taken from Rubio.
Finally made a formal What is a Word puzzle after the Grammy puzzle!
If a word conforms to a special rule, I call it a Romeo Word™.
Use the following examples below to find the rule.
$$ % set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ Romeo }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Words}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2019.05.15}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{ achieve }&\text{ obtain }\\ \hline \text{ amphibian }&\text{ reptile }\\ \hline \text{ audiotape }&\text{ cassette }\\ \hline \text{ collapsing }&\text{ erect }\\ \hline \text{ cytomegalic }&\text{ retinitis }\\ \hline \text{ emu }&\text{ ostrich }\\ \hline \text{ epsilon }&\text{ echo }\\ \hline \text{ labdanum }&\text{ oakmoss }\\ \hline \text{ metal }&\text{ plastic }\\ \hline \text{ neighborhood }&\text{ family }\\ \hline \text{ numerical }&\text{ text }\\ \hline \text{ parasigmatism }&\text{ pronounce }\\ \hline \text{ restaurant }&\text{ inn }\\ \hline \text{ toxic }&\text{ poisonous }\\ \hline \text{ typothetae }&\text{ printers }\\ \hline \end{array}$$
