ImpactLex (Glossary)
What Is ImpactLex?
ImpactLex is ImpactMojo's searchable glossary of 500+ development terms — acronyms, concepts, formulas, frameworks, and case study references that development professionals encounter daily.
It works as a standalone Progressive Web App (PWA), meaning you can install it on your phone and use it offline — handy when you're in the field and need to look up what "DALY" means or how a Gini coefficient is calculated.
Access: Free — Open ImpactLex

How Educators Can Use ImpactLex
As a Workshop Reference
Project ImpactLex during sessions so participants can look up unfamiliar terms in real time. Development jargon is a real barrier — having a searchable reference reduces the "I don't want to ask what that means" problem.
As a Study Aid
Assign participants to learn 5–10 new terms per week from ImpactLex. The contextual definitions help practitioners build vocabulary that connects to their actual work.
Alongside Courses
Each ImpactMojo flagship course has its own interactive lexicon. ImpactLex complements these with a broader, cross-cutting glossary that spans all tracks.
For Report Writing
When participants are writing proposals or reports, ImpactLex helps them use terminology correctly. Misusing terms like "output" vs. "outcome" or "monitoring" vs. "evaluation" is common — ImpactLex provides clear definitions.
Tips
Install the PWA for offline access — especially useful for field-based staff who may not have reliable internet.
500+ terms and growing — if you can't find a term, contact hello@impactmojo.in to suggest additions.
Use alongside course lexicons — flagship courses have specialised glossaries; ImpactLex covers the broader development vocabulary.
