paraplasmn.

Brit.

/ˈparəplaz(ə)m/, U.S.

/ˈpɛrəˌplæz(ə)m/

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: para- prefix¹, -plasm comb. form.

Etymology: < para- prefix¹ + -plasm comb. form, after German Paraplasma (see paraplasma n.). With sense 1b, compare earlier metaplasm n.² With sense 2, compare earlier paraplastic adj.

Now rare.

1. Cell Biology.

a. The cytoplasmic matrix of a cell. disused.

ΚΠ

1883 Proc. Royal Soc. 1882–3 34 20 The spaces of the protoplasmic network are occupied by paraplasm or interfibrillar substance.

1898 Jrnl. Royal Microsc. Soc. 520 There is a hyaline substance (paraplasm) in the interstices of the plasmosome system.

1907 C. von Noorden et al. Metabolism & Pract. Med. I. 333 Must we allocate the so-called organization and vital properties to the cellular spongioplasm, or to the fluid constituents which occupy the interstices of the former—the paraplasm?

b. Cytoplasmic inclusions (vacuoles, granules, crystals, etc.). Cf. earlier metaplasm n.² Now rare.

1887 Amer. Naturalist 21 30 A primary and a secondary plasma,—the former the protoplasm proper, the latter the deutoplasm (paraplasm, metaplasm, etc.).

1891 Quain's Elem. Anat. (ed. 10) I. ii. 174 The terms ‘deutoplasm’ and ‘paraplasm’..have sometimes been applied to materials contained within a cell, which are not considered to constitute a part of the actual protoplasm.

1915 A. P. Mathews Physiol. Chem. 11 (caption) Passive bodies (metaplasm or paraplasm) suspended in the cytoplasmic meshwork.

1958 Ecology 39 156/2 The inanimate parts of the organism..can be discerned just as in the cell the paraplasm can be distinguished from the protoplasm.

1969 Proc. Royal Soc. B. 173 5 Even the so-called paraplasm (reserve material present in eggs and other cells) is more ‘alive’ today than it was a few years ago.

†2. Medicine. Abnormal tissue, esp. a neoplasm or malformation. Obsolete. rare.Apparently only attested in dictionaries or glossaries.
