-tje

Etymology
From earlier, from , from , which is the ancestor of the suffixes , , (and its subvarieties: , , , ) and 🇨🇬. All forms descend from the, , itself a double diminutive produced by combining , +. The change from k to tj is the result of a palatalization of -kijn in North Holland in the 13th or 14th century. Cf. also German, English.

Usage notes

 * The use of this suffix is very productive in Dutch and has led to the creation of quite a few lexicalized forms, i.e. the diminutive has acquired a meaning of its own.
 * Sometimes attached to given names, yielding two possible outcomes:
 * A hypocoristic given name of the same gender, such as (from ),  (from ) or  (from ).
 * A feminine name derived from a masculine name. Examples include, , both feminine names, deriving from the masculine names and  respectively.
 * Informally, this suffix may be attached to adjectives to yield a noun that is not necessarily diminutive, but has derogatory and/or familiar connotations: e.g.s from,  from ,  from  and  from.
 * The suffix takes different variant forms according to the stress and final consonant or vowel of the root it is added to. This is mostly due to of the suffix to the previous consonant. Note that in each case, the actual sound that the word has matters, not the letter(s). Loanwords that retain a silent -e therefore behave as though they ended with the letter before it.
 * -je is added to words ending in:
 * A fricative or plosive (-b, -c, -d, -f, -g, -ch, -k, -p, -q, -s, -sj, -t, -v, -x, -z)
 * Examples: briefje, hokje, visje, doucheje (final sound is -sj), raceje (final sound is -s)
 * -etje is added to words ending in:
 * A stressed short vowel followed by a sonorant (-l, -m, -n, -ng, -r).
 * Examples: pilletje, lammetje, bloemetje (also bloempje as the vowel was originally long), mannetje, vriendinnetje, dingetje, torretje
 * -tje is added to words ending in either:
 * A stressed long vowel or diphthong or any unstressed vowel (-a, -e, -i, -o, -u, -y), or:
 * the above, followed by a sonorant except m or ng (-l, -n, -r).
 * Examples: vrouwtje, autootje, kuiltje, appeltje, maantje
 * -pje is added to words ending in:
 * A stressed long vowel or diphthong or any unstressed vowel followed by m
 * Examples: boompje, duimpje, bloempje (also bloemetje as the vowel has since become short), bodempje
 * -kje is added to words ending in:
 * A stressed long vowel or diphthong or any unstressed vowel followed by ng
 * The -g is removed, so that the resulting word ends in -nkje.
 * Examples: koninkje, houdinkje
 * In informal speech, -ie, -pie and -kie may be used instead of -je, -pje and -kje. This substitution is mandatory in a number of words, particularly in diminutives derived from an adjectival base (such as, , and so forth).
