Along these lines, for the case of intron sequence evolution, the authors consider the most general time-reversible dinucleotide model.

Neighboring nucleotides exert a striking influence on mutation, with the hypermutability of CpG dinucleotides in many genomes being an exemplar.

So this is illustrated with a single dinucleotide with two states.
-
Differences in size of as little as one dinucleotide can be detected.

So here is our dinucleotide, slightly skewed, but OK.

Some of the conclusions of this paper may be influenced by their choice of the dinucleotide mutation rate:

Now we generalize by defining a dinucleotide rate matrix as follows:

The basis of this polymorphic variation is a difference in the number of dinucleotides within (CA)n and other simple sequence repeats.

In real biological sequences, the frequencies of dinucleotide and higher-order tuples are not products of their monomer frequencies.

Two CA dinucleotide repeats (SM7 and SM5B) were detected in cosmic cllE.

Surface Forms
Morphology
dinucleotide = nucleotide (transparent) = di + nucleotide
Formed by the productive numeric prefix 'di-' meaning 'two' plus 'nucleotide'; meaning 'two nucleotides joined' is a direct morphological combination (though the term is technical).
Etymology
Dinucleotide breaks into di- meaning 'two', as in bicycle, and nucleotide, from nucleus meaning 'center', which names the small parts that make up DNA. So a dinucleotide is simply two nucleotide 'units' joined together.
