Tips

grammar
因 works in cause-effect patterns: 因为...所以... (because...therefore...). Key compounds: 因为 (because), 原因 (reason), 因此 (therefore), 因素 (factor). In formal writing, 由于 (due to) is often preferred over 因为.

Components

radical
囗 wéi
enclosure (radical)
Outer enclosure radical - the indexing radical, the big square-frame 囗 (not the small 口 mouth). Here it represents a sleeping mat or confined space. Same enclosure surrounds 国 country, 园 garden, 围 to surround, 困 trapped. The wrapper signals 'something contained inside a defined boundary.'
semantic
大 dà
big; person (semantic)
Inner 大 - the frontal-stance person figure with arms outstretched. Inside the enclosure it pictures a person lying on a mat, the original concrete sense of 因 ('sleeping mat, foundation'). From 'foundation, what one rests on' came the abstract 'cause, reason' that dominates modern usage.
