"The Word" works very nicely.
It's a free, simple, basic, offline reader.
"The Word" looks like it will be perfect for anyone who wants a few basic digital tools for reading Greek, has a computer, but does not have reliable (or cheap) Internet access.
Click on a word and get a definition from Abbott-Smith.
Scroll over any Bible reference in Abbott-Smith and see it in either Greek or English.
Scroll over any abbreviation or referenced work in Abbott Smith and see an explanation.
See Greek and and an English translation side-by-side (linked scrolling).
For the rare person who would need a simple offline reader, I'll make some notes on my installation experience:
The whole installation and set up took me only an hour.
The whole installation was only 350MB. The downloads are light.
An option during set up is to put it on a flashdrive. It's easy and works fine.
The entire installation and customization can be copied wholesale to another flashdrive.
During installation, by default it will load about ten "add-ons." I wasn't interested in any of them and unchecked them. I downloaded and loaded only a few add-ons: SBL, WHNU, LEB, and AMGL.
SBL = new Greek text from Society for Biblical Literature I found that I could not consistently click and get a definition using SBL. I installed WHNU with Strong's numbers and parsing as a work-around. I set up the windows to show SBL on one pane and WHNU on another. This works fine. Using WHNU alone is not an option. The inline numbers make it impossible to read properly and the Greek text has no accents.
LEB = Lexham literal translation.
AMGL = Abbott-Smith, an old, but good, basic New Testament Greek dictionary. Within the definition, many links are given to other places in the NT where the word is used.
WHNU = Wescott-Hort = Greek text (no accents, old version, but tagged)
Linking in THE WORD works by pane, not by book. You need to link from pane A to pane B and again from pane B to pane A.
It looks like the same could be done to make this also serve as a Hebrew offline reader, but I haven't looked into it yet.
