What's a mnemonic for remembering the characters in 建议 and 意见? This is a little bit embarrassing, considering I'm currently studying HSK6-level content, but I cannot memorize how to write the HSK4 words:

建议 (jiàn​yì​)
CC-CEDICT: to propose / to suggest / to recommend / proposal / suggestion / recommendation / CL: 個｜个, 點｜点
意见 (yì​jiàn​)
CC-CEDICT: idea / opinion / suggestion / objection / complaint / CL: 點｜点, 條｜条

So...
Question: What's a mnemonic for remembering the characters in 建议 and 意见?
Just remember:
建立 - erect
议論 - theory
建议 (raise theories) --&gt; to suggest (v) --&gt; suggestion (n)
~
意 - mind
见 - see
意见 (mind see) --&gt; idea ; opinion
Just associate the single characters in these compound words with other related compound words. In short, cross reference them
