In the spirit of the What is a Word™/Phrase™ series started by JLee, a special brand of Phrase™ and Word™ puzzles.
If a word conforms to a special rule, I call it a Resilient Word™.
Use the following examples below to find the rule.
$$ % set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ Resilient }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Words}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2019.05.15}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{ PRESENT }&\text{ GIFT }\\ \hline \text{ SUSPECT }&\text{ SUSPICIOUS }\\ \hline \text{ INVALID }&\text{ VALID }\\ \hline \text{ ADDRESS }&\text{ LOCATION }\\ \hline \text{ CONTENT }&\text{ ITEM }\\ \hline \text{ PROJECT }&\text{ REPOSITORY }\\ \hline \text{ INSERT }&\text{ DELETE }\\ \hline \text{ OBJECT }&\text{ CLASS }\\ \hline \text{ RECORD }&\text{ COMPUTER }\\ \hline \text{ COMPOUND }&\text{ AMALGAM }\\ \hline \end{array}$$
And, if you want to analyze, here is a CSV version:
Error 405: Method Not Allowed
The puzzle satisfies the series' inbuilt assumption, that each word can be tested for whether it is a Resilient Word™ without relying on the other words.
These are not the only examples of Resilient Words™; many more exist.
