An Efficient Phrase™ is one where

each of its letters can be drawn as a single line, without lifting the pen or retracing your path. This allows the letters BCDGIJLMNOPSUVWZ. This limits the word more than it might seem because the three most common letters ETA are disallowed.

    $\begingroup$ The only problem is that you can write "E", "T", and "A" without lifting your pen. You have to retrace your line though. $\endgroup$

    $\begingroup$ @CaelanO'Toole Retracing could be considered "not efficient". $\endgroup$

    $\begingroup$ You draw your A's different than I do, as I have no need to lift my pen. Also they look like stars missing a leg. $\endgroup$

Perhaps it's that an 'E'fficient Phrasetm has

no 'ETA' (estimated time of arrival).

Though I would have thought the opposite to be true.


the full list of letters that are missing are: AEFHKQRTXY, which, when rearranged, gives us TRAHKXEFQY*, a common antonym of "efficient".
*not a word
