員Radical: 口 Components: ハ口目貝
Means member (eg. 部員, club member, or 社員, member of a company), and is read with the onyomi いん. One image you could use for it is a person wearing a big signboard, trying to recruit people to come INto the organisation he’s a member of. My classmate also insisted that, if you squint, it looks like a penis - which fits the meaning, 'member', quite well
記Radical: 言 Components: 已言
Means record, or describe, and is read with the onyomi き. A good visualisation is: Someone’s voice is describing something to themselves, to help them record it in their memory (remember the left hand radical is the kanji for voice).
Or, it looks like an open book – the left page has lines of writing, and the right page has a diagram or picture.
