Guide — 2026
A Complete Guide to Armenia (Jp)
Travel, history, alphabet and everyday phrases for a country with almost no Japanese-language material online.
Websites & iOS apps — an independent practice
Reference works for languages and places the web overlooks.
I make guides and dictionaries — for Armenia, for Tajik, for Cabo Verde — the kind of thing that used to be a book, built now as a website you can search and an app you can carry. Each one starts because I wanted it to exist and found that it didn’t.

Eastern Armenian / Japanese Dictionary
The first dictionary of its kind for Japanese speakers: Eastern Armenian headwords, readings and senses, searchable offline in the Armenian script or in kana, with audio recorded by native speakers. Built because the paper equivalent does not exist. Released on 12 August 2026, it spent its first five days at No. 1 in the paid Dictionaries category of the Japanese App Store.
Approach
A guide is finished when a stranger can use it without asking me anything.
Everything here follows the same method. Read the sources — often in three languages, often contradicting each other. Reduce them to something a beginner can hold. Ship it plainly: fast pages, real typography, no accounts, no interstitials, nothing between a reader and the thing they came for.
The sites and the apps are made by one person, which is the constraint and also the point: scope stays small, the material stays accurate, and corrections ship the same day.
About
Yeongho Lee
Linearize is my independent practice for research-led reference projects — writing, structuring and building each one end to end, from the source material through to the front-end and the App Store listing.
The name
Linearize the path to knowledge.
To linearize, in mathematics and engineering, is to bring something nonlinear into a form that can be analysed and worked with. Knowledge behaves the same way. Learning a language like Armenian or Tajik means branching endlessly — find the reference grammar, decode the script, hunt for trustworthy audio, cross-check a dictionary, then check how the word is actually used.
Linearize draws one road through that thicket: start here, go in order, arrive. Not by thinning the subject out — the complexity stays, and so does the rigour — but by making the route to it plain. Complex knowledge, a clearer path; the field can be language, culture, or anything else specialists reach easily and everyone else does not.
