This is actually very easy, I came up with it by myself
So what you gotta do, is memorize up to 3 most important words in a sentence.
Example:
Pierre Joseph Rossier was a pioneering Swiss photographer whose albumen photographs, which include stereographs and cartes-de-visite, comprise portraits, cityscapes, and landscapes.
So from this we can memorize Pierre, photographer and stereographs
After you memorized the 3 words, your mind will just add more words to it, and it’ll make a full sentence.
This might sound absurd, but, go ahead, try it.
