On one hand, Kyler can be seen as a modern invention, created by combining the on-trend sounds of Kyle and Tyler into something new. With this in mind, the meaning would be "tiler of roofs on the narrow spit of land". 
 
Alternatively, Kyler could be an Anglicized form of the Dutch surname "Cuyler ", which may mean "hole, pit", "bowman, archer", "chapel", or "victory of the people" according to different translations.
 
A surname-as-a-given-name, with the on trend sounds of Kai, Kyler became a popular choice from 1986 onwards, when it first debuted in the charts. Remaining in the Top 300 for most of the 2000s, Kyler did drop by 70 places in 2023 - the first time it has fallen so significantly since it entered the Top 1000. 
 
With parents currently favoring Cooper, Colter and Kaizen, Kyler may continue to sink as Kyle did before it - or, it may just be a temporary blip in its popularity.
