home, family; -ist

家乡 Hometown; 

科学家: Scientist (lit. "science-family expert"

Combination of house (宀) and pig (豕) - the quintessential "domestic animal" - which gives plentiful birth. It came to mean a family. This character shows a kind of Chinese humor in favor of prolificacy. 

象

xiang

elephant;

image, shape

象牙 – Ivory; 形象  – Image/figure; 象征 – Symbol

印象 – impression; 现象 – phenomenon; 象素 – Pixel ("image element")

 The trunk (⺈); The head/body (口); 豕 resembles the legs (though unrelated to the pig character 豕)  

Also means shape as an elephant was more of an exotic imaginary creature to the people of the northern China;  elephants are huge, memorable — so they also became symbols of appearance and image in abstract usage

像

xiang

image; be/look like

to resemble

Metaphor: 像…一样 "just like…"; 

a people (亻) sees an elephant (象) and carves an image, similar as the very character (象) resembles an elephant
