端！午！快/安！乐/康！
不管甜粽咸粽，
端午能吃到的就是好粽砸。放假了各位还坚持阅读我们的推送，
小编感激涕零，特在文末奉上了彩蛋，
一点心意，不成敬意，还望笑纳（不喜欢也得给我收下）！闲话少说，先开始学习吧～
3 things you need to know about "com-":
1, It is the word-forming element meaning "together, with";有“一起的”、“共同的”的含义；
2, It is from Latin com "together, together with, in combination," from Proto-Indo-European root *kom- "beside, near, by, with";来自于拉丁语单词com，意为“一起”、“合并”，最初来源于原始印欧语词根*kom-，意为“旁边”、“附近”等；（小编小编什么叫原始印欧语诶？小编莞尔一笑：“你继续往下搓～”）
3, It is reduced to "co-" before vowels and aspirates, assimilated to "cog-" or "con-"before "-g-", assimilated to "col-" before "-l-", assimilated to "cor-" before "-r-", or assimilated to "con-" before "-c-", "-d-", "-j-", "-n-", "-q-", "-s-", "-t-", "-v-".“com-”出现在元音或送气音之前，辅音[m]被省掉，变为“co-”；出现在“-g-”之前，受其影响同化为“cog-”或“con-”；出现在“-l-”前，同化为“col-”；在“-r-”前，同化为“cor-”；出现在“-c-”， “-d-”，“-j-”，“-n-”，“-q-”，“-s-”，“-t-”，“-v-”前，都同化为“con-”。↓"co-", "cog-", "con-", "col-", "cor-" all carry the meaning of "together with, in common".
小编的服务宗旨：
让你见识一个“拖家带口”的“com-”。

co(m)- "together" +
gnoscere "to notice, to know"
Cognition, the act or process of thinking, enables us to process vast amounts of information quickly.

4. confide [kən'faɪd]v. 吐露秘密
fidere "to have faith in someone"
