If I had this app btwn 60's & 80's

I'd have a Masters degree in English at the very least.
I went to Jr college after 1st 4 yrs serving my country in USMC. 72-76. Worked full time, w/ wife, 1 st born, house pmt and 10 plus hrs per day with San Francisco Pepsi Cola Co. Took me 3.5 yrs to receive two AA degrees going to class nights and Saturdays. Graduated 1982. Had my head in several dictionaries from 72- to 82 just for class, had all books you offer on my desk at work, home and spent ALL Saturdays in college library; all Sunday's studying at home.
Today's generations have no clue what they have at their disposal to assist them in balancing studies with work, being a husband, father, employee etc; etc....😞😁🇺🇸. Along with attempting to have a " Life"

Dictionary App

This is one perfect app! I so appreciate this one. I especially appreciate the audible pronunciation of the words you look up, that is such an excellent feature because some words are hard for me to pronounce so with this feature you get the help you need. My Mom was my dictionary for years. My siblings and I would always call on her for spelling help or word definition help. She has since gone on to be with the Lord but with this app, it's like having her here again!! Great job and thank you much!

Essential to me

I love this app and use it constantly. The pronunciation function is particularly useful because of all the foreign words it includes. (I often find words here that are not in my Larousse French dictionary.) The app was an enormously helpful resource for grad school as I could quickly access information while reading or check out suggestions for synonyms while writing papers. Highly recommend!
