How can I add "and" between multiple categories assigned to an entry? I have some entries that have more than one category assigned to them (under the same category group).  For example, Entry X might be assigned to Category A and Category D.   How do I get it to print "Category A **and** Category B" instead of Category A Category B"?
Loop through the categories of the entry, add and if it's not the last loop index, like so:

{% for category in  entry.categoryFieldHandle %}
 {{category.title}} {{ loop.last ? '': 'and '}}
{% endfor %}
