Consider the data below from Syrian Arabic (Afro-Asiatic) (Cowell 1964: 173-4). Segment the words into morphemes, and identify the meanings/functions of the morphemes. What word formation processes are represented in these data? (Hint: Assume that the form for 'he ate' is akkal, that this form has neither prefixes nor suffixes, and that a glottal stop always occurs before a vowel-initial stem.)
\begin{tabular}{|c|c|c|c|}
\hline $7 a k a l$ & The ate' & byaakol & "he ess" \\
\hline Pablet & 'she ate' & btaakd & 'she eats' \\
\hline Pakkalu & they afe' & bysaklu & 'they eat' \\
\hline Pakält & 'you (masc) ate' & btaakd & you (masc) eat' \\
\hline rakátiti & 'you (fem).) ate' & btaabi & you (fem) eat' \\
\hline $\begin{array}{l}\text { Pakaltu } \\
\text { kol }\end{array}$ & $\begin{array}{l}\text { you ( } \beta \mathrm{L}) \text { ate' } \\
\text { 'eat' (masc)? }\end{array}$ & btaaku & you $(p l)$ eat' \\
\hline
