It may seem remarkable that I am a reporter (7)
I believe the answer is:
impress
'it may seem remarkable' is the definition.
The definition suggests a singular noun which matches the answer.
'i am a reporter' is the wordplay.
'i am' becomes 'I'm' (contraction).
'a reporter' becomes 'press' (I can't justify this - if you can you should believe this answer much more).
'im'+'press'='IMPRESS'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for impress that I've seen before include "Affect deeply" , "Mark made by a seal or stamp" , "Produce a strong, lasting impression on" , "Influence - conscript - stamp" , "force to join navy?" .)
