IPA: /ɪkˈsɛlsiər/
KK: /ɪkˈsɛlsiər/
Thin, curled pieces of wood that are often used to protect fragile items during shipping or storage.
The fragile vase was carefully packed in a box filled with excelsior to prevent any damage.
Excelsior is derived from the Latin word "excelsus" (meaning lofty or elevated) and the suffix "-ior" (indicating a comparative degree). Together, these parts convey the idea of something that is higher or more elevated, hence the meaning of 'ever upward' or 'still higher.'
Think of 'lofty' ('excelsus') to remember that 'excelsior' means ever upward or striving for higher things.
