Ha, sorry for sounding harsh, and thanks for pointing me to "product"! It's a
good test case indeed.

In the current model, a Lexeme has forms and senses. Forms don't have senses
directly, the meanings should apply to all forms. This means lexemes have to be
split with higher granularity:

* product (English noun) would be one lexeme, with "products" being the plural
form, and "product's" the genitive, and "products'" the plural genitive. Sense
include the ones you mentioned.
* (to) produce (English verb) would be another lexeme, with forms like
"produces", "produced", "producing", etc, and senses meaning "to create", "to
show", "to make available", etc
* production (English noun) would be another lexeme, with other forms and 
* produce (English noun) would be another
* producer (English noun) would be another
* produced (English adjective) another

These lexemes can be linked using some kind of "derived from" statements.

That's the plan, yes: Have lexemes (L...) on wikidata, which wrap the structure
of forms and senses, and has statements for the lexeme, as well as for each form
and each sense.

We don't currently plan a "super-structure" for wrapping derived/related lexemse
(product, produce, production, etc). They would just be inter-linked by

The link I suggest is between items (Q...) and lexemes (L...), both on Wikidata.
