DrillKit is an AI-powered tool that turns your online lesson chat from Zoom, Google Meet, Skype, or Microsoft Teams into professional, print-ready ESL lessons in under 30 seconds. It automatically extracts vocabulary, generates exercises (gap-fill, error correction, vocab match, word formation, and more), and produces beautiful PDFs tailored to the student's CEFR level and native language.

Does DrillKit support Zoom chats?

Yes! Simply copy the chat text from your Zoom, Google Meet, Skype, or Microsoft Teams lesson and paste it directly into the input area. You can also paste vocabulary lists or handwritten notes. DrillKit's AI strips out timestamps, sender names, and other noise automatically.

Can I export lessons to PDF?

Absolutely. Every lesson is generated as a high-quality, print-ready PDF. Pro users can also export to Google Docs and customize branding with their school logo and accent colors.

Which languages are supported?

DrillKit supports translations in 11 languages: Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Arabic, Turkish, and Russian. The AI auto-detects the student's native language from the chat transcript.

What exercise types can DrillKit generate?

DrillKit generates 11 exercise types: Gap Fill, Vocab Match, Error Correction, Sentence Completion, Multiple Choice, Word Scramble, Sentence Reorder, Translation, Word Formation (Cambridge Part 3), Key Word Transformation (Cambridge Part 4), and Dialogue Builder.

How does the AI extract vocabulary from chat transcripts?

The AI scans your pasted chat transcript, strips out noise (timestamps, reactions, media placeholders), identifies teachable vocabulary, phrasal verbs, idioms, and student errors, then scores each item by relevance. You review and select the best items before generating exercises.

Is DrillKit free to use?

Yes! The free plan includes 20 generations per month with full access to all 13 exercise types, all lesson styles, and custom branding. The Pro plan ($5.99/month or $4.00/month billed yearly) unlocks unlimited generations and priority AI processing.

Can I customize the lesson with my school branding?

Pro users can add their school or institution name, choose custom accent colors, select from 5 lesson styles (Standard, Classic, Modern, Playful, Academic), and add footer text to every generated lesson.

Teaching Word Formation and Morphology in English | DrillKit Blog

The Word Formation Advantage

English derives much of its vocabulary through systematic morphological processes. A student who learns that 'un-' negates, '-able' means 'capable of being,' and '-ness' converts adjectives to nouns has simultaneously acquired a key to thousands of words they've never encountered.

Morphological awareness — the ability to analyze and manipulate the structure of words — is one of the strongest predictors of vocabulary growth rate. Teaching it explicitly is one of the highest-ROI vocabulary interventions available.

The Four Word Formation Processes

1. Affixation (prefixes and suffixes)
Prefixes: un- (unhappy), dis- (disagree), re- (redo), mis- (misunderstand), pre- (preview), over- (overdo)
Suffixes: -tion (decision), -ment (development), -ness (kindness), -able (comfortable), -ful (hopeful), -less (helpless)

2. Compounding
Joining two or more words: blackbird, notebook, breakthrough, overwhelm, suitcase. In English, the stress pattern distinguishes compounds from phrases: 'BLACK bird' (compound) vs 'black BIRD' (modifier + noun).

3. Conversion (zero derivation)
Changing a word's grammatical function without adding an affix: 'Google' (noun → verb: 'I'll Google it'), 'text' (noun → verb: 'text me'), 'download' (noun and verb), 'impact' (controversial as verb: 'this impacts the budget').

4. Blending and clipping
Blending: brunch (breakfast + lunch), Brexit (Britain + exit), smog (smoke + fog). Clipping: ad (advertisement), fridge (refrigerator), gym (gymnasium). These reflect language evolution in real time.

Key Prefixes and Their Meanings

❌

Negation Prefixes

un-, dis-, non-, in-/im-/ir-/il- — each attaches to different word classes with subtle rules

🔄

Reversal/Repetition

re- (redo), de- (defrost), un- (untie) — reversing or repeating an action

📊

Size and Quantity

over- (overdo), under- (underperform), mini- (minibar), mega- (megaproject)

Teacher Tip

“When teaching a new word, always ask: 'What family does this word belong to?' Teach students to immediately check for noun, verb, adjective, and adverb forms. A student who learns 'decide' should simultaneously learn 'decision, decisive, decisively, indecision, indecisive.' Four words acquired for the price of one.”

Frequently Asked Questions

Do all words have analyzable morphology?

No — many high-frequency English words are mono-morphemic (can't be broken down further): big, run, eat, blue. Morphological analysis is most powerful for Latinate and Greek-root vocabulary, which forms the majority of academic and technical English.

Should I teach prefixes/suffixes in isolation or with specific words?

Both. Learn the prefix meaning in context of 3-4 specific words, then practice deriving new words using the rule. 'Dis- means not or reversal: dishonest, disagree, dislike. What might disobey mean? What about disorganized?'

Is Cambridge Part 3 (Word Formation) a useful teaching framework?

Excellent — Cambridge word formation tasks expose learners to affixation patterns in context, with the pressure of formal testing that motivates systematic attention. Use authentic Cambridge Part 3 items as teaching materials alongside exam preparation.
