glutinous

glutinous is pronounced as "gloot-n-uhs"...so it sounds like a glue (i.e gum) which is sticky or viscous

sounds like a glue +tino(ALL THE THREE)+us…you have to paste all the three photographs on U.S visa form with STICKy GLUE……

Gluten = starch = sticky

rhymes with gluinous Glue means sticky. So glutinous means sticky
