If a word conforms to a special rule, I call it a Baguette Word™.
Use the examples below to find the rule.

$ \begin{gather*} % 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\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\textbf{Baguette Words}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not Baguette Words}^{\;\!™}\Pad\ } \smash{\lower{29px}\bbox[lightblue]{\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{ vase}&\text{ bowl}\\ \hline \text{ abandon}&\text{ leave}\\ \hline \text{ announce}&\text{ declare}\\ \hline \text{ Canada}&\text{ Singapore}\\ \hline \text{ air}&\text{ wind}\\ \hline \text{ exchange}&\text{ stack}\\ \hline \text{ algorithm}&\text{ mathematics}\\ \hline \text{ legend}&\text{ myth}\\ \hline \text{ fork}&\text{ knife}\\ \hline \text{ address}&\text{ location}\\ \hline \text{ adorable}&\text{ cute}\\ \hline \hline \end{array} \end{gather*}$

Answer 1

My guess is:

A Baguette Word™ is a word that has a French origin.

Reasoning:

(All the etymologies stated below are from googling "(word) etymology" unless stated otherwise)

For the Baguette Words™:
vase: late Middle English: from French, from Latin vas ‘vessel’.
abandon: late Middle English: from Old French abandoner, ...
announce: late 15th century: from French annoncer, from Latin annuntiare, ...
Canada: from Wiktionary: "From French Canada, from the Laurentian kanata (“village, settlement”)."
air: Middle English (in air (sense 1 of the noun)): from Old French air, from Latin aer,...
exchange: late Middle English: from Old French eschange (noun), eschangier (verb), based on changer (see change)...
algorithm: late 17th century (...): variant (...) of Middle English algorism, via Old French from medieval Latin algorismus .
legend: Middle English (in the sense ‘story of a saint's life’): from Old French legende, from medieval Latin legenda ‘things to be read’, from Latin legere ‘read’.
fork: Old English forca, force (denoting a farm implement), based on Latin furca ‘pitchfork, forked stick’; reinforced in Middle English by Anglo-Norman French furke (also from Latin furca ).
address: Middle English (as a verb ...): from Old French, based on Latin ad- ‘towards’ + directus (see direct). ...
adorable: early 17th century (in the sense ‘worthy of divine worship’): from French, from Latin adorabilis, from the verb adorare (see adore).

For the Not Baguette Words™:
bowl: Old English bolle, bolla, of Germanic origin; related to Dutch bol ‘round object’, also to boll.
leave: Old English lǣfan ‘bequeath’, also ‘allow to remain, leave in place’ of Germanic origin; related to German bleiben ‘remain’.
declare: Middle English: from Latin declarare, from de- ‘thoroughly’ + clarare ‘make clear’ (from clarus ‘clear’).
Singapore: from Wiktionary: "From Malay Singapura, from Sanskrit सिंहपुर (siṃhá-pura), from सिंह (siṃha, “lion”) +‎ पुर (pura, “city”). "
wind: Old English, of Germanic origin; related to Dutch wind and German Wind, from an Indo-European root shared by Latin ventus .
stack: Middle English: from Old Norse stakkr ‘haystack’, of Germanic origin.
mathematics: While both google and Wiktionary state the word hes a French origin, etymonline.com gives: "from Old French mathematique and directly from Latin mathematica (plural), ...", so perhaps the problem designer thinks the word is directly from Latin?
myth: mid 19th century: from modern Latin mythus, via late Latin from Greek muthos .
knife: late Old English cnīf, from Old Norse knífr, of Germanic origin.
location: late 16th century: from Latin locatio(n- ), from the verb locare (see locate).
cute: early 18th century (in the sense ‘clever, shrewd’): shortening of acute.
With no "French" in sight (except for "mathematics": see above).

It is called Baguette Word™ because:

"Baguette" is usually taken as pertaining to French culture.
