Seems RTÉ will be in disarray for part of the year (8)
I believe the answer is:
semester
'year' is the definition.
(thesaurus)
'seems rte will be in disarray for part of' is the wordplay.
'seems rte' anagrams to 'SEMESTER'.
Though, I'm unsure how this is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for semester that I've seen before include "Steers me towards university term" , "part of the school year" , "Half-year university session" , "Academic half-year term" , "Half US academic year" .)
