how can we add a suffix (such as a plural "s") to a variable that we call in println?
ex:
*code*
for bird in ["crow", "parrot", "bluejay"]
println("$bird are birds") #how do we add an "s" to $bird without
having a space inbetween
*desired outcome:*
crows are birds
parrots are birds
bluejays are birds
