Second-language speakers of French are distributed throughout many parts...

, for both male and female names, hypocorisms are most commonly formed by dropping the last syllable:

• Catherine → Cathy
• Christelle → Chris
• Christophe → Chris
• Frédéric, Frédérique → Fred
• Grégory, Grégoire → Greg
• Jean-Michel → Jean-Mi
• Joannie → Jo
• Marie-Charlotte → Macha
• Marie-Josée → Marie-Jo
• Maxime → Max
• Michaël → Mic
• Philippe → Phil
• Stéphane → Steph
• Stéphanie → Steph

Dropping the first syllable is also attested:

• Christophe → Tophe

Sometimes, only central syllables are kept:

• Augustin → Gus
• Emmanuel → Manu
• Emmanuelle → Manu

Another method commonly used is doubling one syllable of the name:

• André → Dédé
• Annie → Nini
• Augustin → Tintin
• Christine → Kikine
• Christophe → Totophe
• Joseph → Jojo
• Julie → Juju
• Louis → Loulou
• all female names ending in -tine → Titine

For male names, the ending -ot is attested, although its use is rather dated:

• Charles → Charlot
• Jean → Jeannot
• Jules → Julot
• Pierre → Pierrot

It was also sometimes (but rarely) used for females:

• Marguerite → Margot

The ending -et for males was used around the Renaissance, and is now obsolete:

• Henri → Henriquet
• Jacques → Jacquet

For female names, the ending -ette was used in the first half of the 20th century, and even often given as the official name:

• Anne → Annette
• Jeanne → Jeannette
• Marie → Mariette
• Paule → Paulette

Some names in -ette are not actual hypocorisms, but the only existing femalized form of a male name:

• Antoine (male) → Antoinette (female)
• Pierre (male) → Pierrette (female)
• Nicolas (male) → Nicolette (female) (rare and dated) → Colette

The ending -on is rarer, often dated or obsolete, used for both genders:

• Antoinette → Toinon
• Françoise → Fanchon
• Henri → Riton
• Marie → Marion
• Louis → Louison
• Louise → Louison

The ending -ou is also rare:

• Anne → Nanou

A special case is the ending in -ick/ -ic, which is the French writing for the hypocoristic form in Breton

Breton language

Breton is a Celtic language spoken in Brittany , France. Breton is a Brythonic language, descended from the Celtic British language brought from Great Britain to Armorica by migrating Britons during the Early Middle Ages. Like the other Brythonic languages, Welsh and Cornish, it is classified as...

 "-ig", used for both genders. The "-ig" form in Breton means "Little ...". This diminutive, in its French form of "ick" or "ic", became in vogue for official names in the second half of the 20th century:

• Annick (original in Breton: Annaig), from Anne
• Soizic (original: Soazig), from Frañsoaz, the Breton writing for the French "Françoise"
• Loïc, probably from the French Louis
• Yannick (original: Yannig), from Yann, meaning "John" in Breton

In Breton, the diminutive form "...ig" can be given to any kind of names, nouns or adjectives, (un tammig, a few), while in French it relates only to Christian names.

The name Soazig shows more than the ending "ig". Often in Breton a hypocoristic form of a Christian name can be made by putting away the first syllable. "Frañsoaz" becomes a familiar "Soaz" then, given to a child, the name is "Soazig", but not as an official name. This is also a difference between French and Breton: the diminutive ending "...ig" in Breton is only used as a temporary form for young children, while "...ick" is official and permanent in French names, and has lost his sense of a diminutive.

For words, French often produces hypocorisms either by truncating a word after the letter o, or by chopping off the end of the word and adding an o: McDo from McDonalds; gynéco from gynécologue; dico from dictionnaire; dodo (childish word for sleep, from dormir, to sleep); écolo from écologiste; coco from communiste; catho from catholique; psycho from psychologie.

The ending -oche (with or without an intervening consonant or phoneme to make it easier to pronounce) is also sometimes used: cinoche (cinéma), MacDoche (McDonalds), fastoche (easy-peezy, from facile, easy). Words or names may also be shortened or abbreviated without an O: fixs from fixations, 'ski bindings'; Jean-Phi from Jean-Philippe; amphi from amphithéatre (large classroom or lecture hall); ciné (another informal word for cinéma). These words are familiar/informal versions of the underlying words.

The connotation of familiarity (my friend Jean-Phi, as opposed to my new work colleague Jean-Philippe; cinoche, the place I often go for entertainment, as opposed to cinéma, the neutral word for a movie theater) is what makes them hypocorisms.

German

Hypocorisms of first names are commonly based on truncation, only keeping the first (Max) or last (Hans) syllable(s), sometimes in contracted form as these examples show. Often the ending -i is added to these truncated nameforms. The name might also undergo a sound shift (Sepp). Further diminutives can be added with the suffixes -lein or -chen, e. g. Gretchen as a diminutive for Grete.

• Anna, Anne → Anni
• Anton → Toni
• Georg → Schorsch (mostly Bavarian and Swiss German)
• Ignaz → Nazi (Bavarian; out of use)
• Johannes → Hannes → Hans → Hansi
• Josef, Joseph → Sepp (Bavarian), Jupp (Rhinelandic)
• Karl → Kalle, Kalli
• Margarete → Grete
• Maximilian → Max
• Susanne, Susanna, Susann → Susi
• Therese, Theresia → Resi (mostly Bavarian)
• Ulrich → Uli (Ueli in Swiss German)
• Wilhelm → Willi

Sometimes female names may have the ending -el instead of -i, or any other shortening, especially in southern Germany:

• Barbara → Babsi → Bärbel
• Ursula → Uschi, Ulla, Ursel
• Christina, Christine → Trina, Trine (northern Germany), Tina, Tine → Christel

An ending for nicknames, sometimes considererd “typical german” is -z:

• Friedrich → Fritz (but compare the much softer Fidi from northern Germany)
• Heinrich → Heini, Heinz, Hinz
• Konrad → Kunz

Hungarian

Hypocorisms of first names are commonly based on truncation, only keeping the first (Kat-; Jul-) syllable, sometimes in contracted form as these examples show. Often the ending -i is added to these truncated nameforms (Kati, Laci, Julcsi, Ági, Feri). Further diminutives can be added with the suffixes -csi or -ka, e. g. Julcsi and Lacika as a diminutive respectively for Júlia and László. The shorter forms are often can be given as first names in their own right (Tóni, Lili, Béni etc.)

• Anna (Anne) → Ani(ka)
• György (George) → Gyuri
• János (John) → Jancsi
• József (Joseph) → Józsi
• Károly (Charles) → Karcsi
• Margit (Margaret) → Manyi, Manci
• Zsuzsa (Susan) → Zsuzsi
• Teréz (Theresa) → Trézsi (obsolete)
• Vilmos (William) → Vili

Italian

Some diminutive forms can be further modified by abbreviation depending on the region. Some diminutive can be abbreviation of more than one name (ex. Pippo' can be Giuseppe or Filippo, Lele can be diminutive of pretty much all the names which end in "ele": Gabriele, Raffaele, Emanuele).

As catholic tradition until 1945 a child was forced to be named after a saint or a byblical persona, therefore some people have an Anglosaxon Hypocorism which derives from a very obsolete italian name ex. Calogero, Gerardo or Virginio become Jerry, Genoveffa becomes Jenny, Anastasia becomes Stacy and Maria Grazia becomes Grace.
