Grammar Nerd?

Fascinated by grammar rules of your native language or a language you are studying?

Bliu Bliu is mapping the grammar for all languages so that a computer could understand the connections between words when they are presented in different forms but with the same of very similar meaning:

  • car / cars
  • play / plays / played / playing

We are looking for rules that can describe a beaviour applicable to multiple forms of the same word.

Example: english plural

In English, the rule +s (add the letter 'S' at the end of a word) explains, for most of the names, how to generate the plural form of the same word.

  • car +s = cars
  • dog +s = dogs

"Add s at the end" is not the only rule as it doesn't apply to all names. A second rule: +es will apply to other words:

  • kiss +es = kisses
  • dish +es = dishes

…one more rule: +ies

  • cherr +y = cherry // cherr +ies = cherries
  • lad +y = lady // lad +ies = ladies

3 rules will cover most of the names and describe the singular and plural form

  • . (singular) / s (plural)
  • . (singular) / es (plural)
  • y (singular) / ies (plural)

How to Help

Depending how nerd you are or how much you are familiar with coding...

MAP the RULES you Know

(Nerd level)

1. Open this url ( ) 2. Pick a word on the list that we haven't described yet 3. Send us an email with the possible forms (

Example: "naturally" is a word we haven't described You could send us this rule:

. adjective form +ly adverb

This rule would apply to many other words in English and Bliu Bliu would know that there is a grammatical difference between natural and naturally but basically they have the same or similar meaning.

  • general +ly = generally
  • practical +ly = practically

Then you might realize that this rule doesn't apply to words ending with "e" as simple

  • simple + ly = simplely (not an english word)

The rule in this case would be

  • +e - adjective (simpl +e)
  • +y - adverb (simpl +y)
