BASH:Check if variable value begins with [

Question

I am using [[ $each_word == [* ]] right now. It doesn't cause an error, but I am not sure if it is safe. Also does this cover all cases for words that begin with '['

It appears that the parser treats [ literally instead of as the start of a bracket expression because the bracket expression ends prematurely. To be safe, I would quote it to make explicit that you want a literal [:

[[ $each_word == "["* ]]
