Could someone smart please write out all the radicals of which this character comprised of? I’d be very much grateful
You can easily find it by searching 谢读音 xie4 du2 yin1 and you can then find it in any of the online dictionary links under the heading 部首 bu4 shou3 (radical). The radical for 谢 is the two-stroke part at the left hand side, it is known as 言字旁 yan2 zi4 pang2, since it is a "short form" of 言 which means speech, or something related to oratory skills and such.
An interesting to note is that there are "capital letter" versions of words （大写 da4 xie3）, at least for the numbers 1 to 9, that I know of, anyway. With the same pronunciation they are, corresponding to （小写 xiao2 xie3） 一二三四五六七八九十 yi1 er4 san1 si4 wu3 liu4 qi1 ba1 jiu3 shi2: 壹贰叁肆伍陆柒捌玖拾.
