 [flek´shun]
1. the act of bending or the condition of being bent.

plantar flexion bending of the toes or foot downwards toward the sole.

flex·ion

(flek'shŭn), [TA] Avoid the misspelling flection.
1. The act of flexing or bending, for example, bending of a joint to approximate the parts it connects; bending of the spine so that the concavity of the curve looks forward.
2. The condition of being flexed or bent.

flexion

[flek′shən]
Etymology: L, flectere, to bend
1 a movement allowed by certain joints of the skeleton that decreases the angle between two adjoining bones, such as bending the elbow, which decreases the angle between the humerus and the ulna. Compare extension.
2 a resistance to the descent of the fetus through the birth canal that causes the neck to flex so the chin approaches the chest. Thus the smallest diameter (suboccipitobregmatic) of the vertex presents.

flexion

a movement which decreases the joint angle between two ventral surfaces of the body, e.g. bending the elbow or knee, tilting the head forwards. flexor muscles those with this action, e.g. biceps, hamstrings. Opposite of extension. Figure 1.

Paula (2007), com o objetivo de estudar conhecimentos implicitos e explicitos sobre a dimensao morfologica, derivacional e flexional, investigou dois grupos de criancas brasileiras de ambos os sexos, sendo 50 dos primeiros anos escolares (primeira e terceira series) e 210 de anos escolares mais avancados (quinta e setima series).
Por lo que respecta a Gamez, si bien este mismo analisis pudiera ser aplicable a la terminologia, no en cambio al concepto, puesto que no se entiende el caso --segun ya hemos comentado-- como categoria flexional (formal), sino como trasunto de funciones sintacticas, con independencia de los medios materiales empleados para su cristalizacion.
Dentre as hipoteses apresentadas para a perda de morfologia flexional e de regras de concordancia, destacam-se aqui a de Lucchesi (2003) e a de Naro; Scherre (2003a).
Nele estao, a forma que se refere a primeira pessoa, ou seja, o falante que leva o verbo para a forma flexional de 1a pessoa e o que se refere aos outros, com o falante incluido ou nao, sem a oposicao de singular/ plural na flexao verbal, conforme os exemplos:
In contrast, the s or x of the plural (/z/) is the strongest and foremost among the flexional consonants, and the only one that can outweigh grammar and even logic.
En concreto, la categoria del aspecto es de suma importancia, pues impone ciertas restricciones: por ejemplo, a la combinacion de mientras (que) con verbos desinentes o puntuales con un aspecto flexional perfectivo y terminativo: *mientras salio, *mientras se ha muerto, o con ciertos verbos de estado que en preterito adquieren un contenido ingresivo: *mientras conocio (de modo que en estos casos la coexistencia de dos eventos se suele expresar con cuando).
Un elemento que no sabemos si definir pronominal, por lo menos en un sentido estrictamente sincronico, y que mejor se diria afijo flexional, senala la concordancia con el objeto, mientras que otro senala la concordancia con el sujeto, como en (9a), y tambien con la expresion del nominal como en (9b), cuando no se proceda a incorporacion, como en (9c).
A aquisicao precoce das Codas atonas finais (patos) no PE, imune ao efeito da proeminencia acustica das estruturas tonicas, tem sido interpretada como o produto da interface fonologia-morfologia, colocando-se a hipotese de esta Coda em final de palavra ser processada pelas criancas portuguesas como proeminente por lhe ser inerente informacao de dois tipos: fonologica (ramificacao da Rima, estrutura nao disponivel no inicio da aquisicao) e morfologica (marcacao do numero plural; o final de palavra em PE esta associado a presenca de informacao flexional em diferentes classes de palavras, o que a torna gramaticalmente proeminente).
Para a sua especificacao temporal e necessario o uso de perifrases com outro verbo que carregara o seu morfema flexional e assim, sua marca temporal.
Nesse caso, em um enunciado como 'meu gato dorme', o nome 'gato', ao se unir ao possessivo 'meu', formaria sintaticamente um NP passivel de ser tomado como argumento do sintagma flexional 'dorme'.
