Thank you for your thoughtful response @countrygirl.

Lets try this.....I am going to reword your sentence....

I wondered if it means that being short on vocabulary limits our ability to express ourselves and therefore go further in thought on any given subject.

Like not being able to discuss a subject without a technical vocabulary.

ie...automobiles/catalytic converter......cryptocurrencies/delegated proof of stake, DPOS...etc.

......or not being able to write a poem, prose or story as one would wish for lack of vocabulary....etc.

Appreciate your query and the opportunity to discuss this principle. ^__^

Thank you for your kind words regarding the photographs.......yes....letters make words....words make sentences.....sentences make paragraphs and paragraphs make chapters...chapters turn into books.

Lovely posts you have out there.

All the best to you.

Cheers.
