  Languages can encode temporal subordination lexically, via subordinating
conjunctions, and morphologically, by marking the relation on the predicate.
Systematic cross-linguistic variation among the former can be studied using
well-established token-based typological approaches to token-aligned parallel
corpora. Variation among different morphological means is instead much harder
to tackle and therefore more poorly understood, despite being predominant in
several language groups. This paper explores variation in the expression of
generic temporal subordination ('when'-clauses) among the languages of Latin
America and the Caribbean, where morphological marking is particularly common.
It presents probabilistic semantic maps computed on the basis of the languages
of the region, thus avoiding bias towards the many world's languages that
exclusively use lexified connectors, incorporating associations between
character $n$-grams and English $when$. The approach allows capturing
morphological clause-linkage devices in addition to lexified connectors, paving
the way for larger-scale, strategy-agnostic analyses of typological variation
in temporal subordination.
