  We investigate the scattered palindromic subwords in a finite word. We start
by characterizing the words with the least number of scattered palindromic
subwords. Then, we give an upper bound for the total number of palindromic
subwords in a word of length $n$ in terms of Fibonacci number $F_n$ by proving
that at most $F_n$ new scattered palindromic subwords can be created on the
concatenation of a letter to a word of length $n-1$. We propose a conjecture on
the maximum number of scattered palindromic subwords in a word of length $n$
with $q$ distinct letters. We support the conjecture by showing its validity
for words where $q\geq \frac{n}{2}$.
