  We investigate the role played by curve singularity germs in the enumeration
of inflection points in families of curves acquiring singular members. Let $N
\geq 2$, and consider an isolated complete intersection curve singularity germ
$f \colon (\mathbb{C}^N,0) \to (\mathbb{C}^{N-1},0)$. We introduce a numerical
function $m \mapsto \operatorname{AD}_{(2)}^m(f)$ that arises as an error term
when counting $m^{\mathrm{th}}$-order weight-$2$ inflection points with
ramification sequence $(0, \dots, 0, 2)$ in a $1$-parameter family of curves
acquiring the singularity $f = 0$, and we compute
$\operatorname{AD}_{(2)}^m(f)$ for various $(f,m)$. Particularly, for a node
defined by $f \colon (x,y) \mapsto xy$, we prove that
$\operatorname{AD}_{(2)}^m(xy) = {{m+1} \choose 4},$ and we deduce as a
corollary that $\operatorname{AD}_{(2)}^m(f) \geq (\operatorname{mult}_0
\Delta_f) \cdot {{m+1} \choose 4}$ for any $f$, where $\operatorname{mult}_0
\Delta_f$ is the multiplicity of the discriminant $\Delta_f$ at the origin in
the deformation space. Furthermore, we show that the function $m \mapsto
\operatorname{AD}_{(2)}^m(f) -(\operatorname{mult}_0 \Delta_f) \cdot {{m+1}
\choose 4}$ is an analytic invariant measuring how much the singularity "counts
as" an inflection point. We obtain similar results for weight-$2$ inflection
points with ramification sequence $(0, \dots, 0, 1,1)$ and for weight-$1$
inflection points, and we apply our results to solve various related
enumerative problems.
