Sample Theme Analysis
Oct 12
One year [[after they got married]] they found their car keys.
Marked Theme: circumstance of temporal Location realised by a nominal group with an embedded clause as Qualifier.
Note: The reason one year after is not a conjunction group, with one year as a Premodifier of after is as follows:
(1) conjunctions form a word class within the primary word class of adverbials [Halliday & Matthiessen 2004: 358];
(2) Premodifiers in adverbial groups are grammatical items — there is no lexical premodification in the adverbial group [op cit: 356];
(3) items serving as Premodifiers in adverbial groups are adverbs of polarity, comparison or intensification [ibid];
(4) all the examples given of Premodifiers in conjunction groups are grammatical items (even, just, not, only), not lexical items [op cit: 358].

The utter ludicrousness of regarding preceding lexical words as Premodifiers within a conjunction group can be seen in the following, with the would-be conjunction group highlighted in bold:
One excruciatingly painful and somewhat hazardous, and not to say chaotic year after they got married… etc

yes, but while i see what you are saying, i’m not necessarily agreeing this is the only way to cut it.

yep, I was only trying to present the most probable way IFG would cut it.
